CVE-2021-22947 | 9 Apple, Debian, Fedoraproject and 6 more | 37 Macos, Debian Linux, Fedora and 34 more | 2024-11-21 | 5.9 Medium |
When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server. | ||||
CVE-2021-22946 | 9 Apple, Debian, Fedoraproject and 6 more | 40 Macos, Debian Linux, Fedora and 37 more | 2024-11-21 | 7.5 High |
A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. | ||||
CVE-2021-22923 | 7 Fedoraproject, Haxx, Netapp and 4 more | 25 Fedora, Curl, Cloud Backup and 22 more | 2024-11-21 | 5.3 Medium |
When curl is instructed to get content using the metalink feature, and a user name and password are used to download the metalink XML file, those same credentials are then subsequently passed on to each of the servers from which curl will download or try to download the contents from. Often contrary to the user's expectations and intentions and without telling the user it happened. | ||||
CVE-2021-22922 | 7 Fedoraproject, Haxx, Netapp and 4 more | 25 Fedora, Curl, Cloud Backup and 22 more | 2024-11-21 | 6.5 Medium |
When curl is instructed to download content using the metalink feature, thecontents is verified against a hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same contentfrom a set of different URLs, potentially hosted by different servers and theclient can then download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload. It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk. | ||||
CVE-2021-22555 | 4 Brocade, Linux, Netapp and 1 more | 27 Fabric Operating System, Linux Kernel, Aff 500f and 24 more | 2024-11-21 | 8.3 High |
A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space | ||||
CVE-2021-22543 | 5 Debian, Fedoraproject, Linux and 2 more | 29 Debian Linux, Fedora, Linux Kernel and 26 more | 2024-11-21 | 7.8 High |
An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation. | ||||
CVE-2021-21381 | 4 Debian, Fedoraproject, Flatpak and 1 more | 5 Debian Linux, Fedora, Flatpak and 2 more | 2024-11-21 | 7.1 High |
Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In Flatpack since version 0.9.4 and before version 1.10.2 has a vulnerability in the "file forwarding" feature which can be used by an attacker to gain access to files that would not ordinarily be allowed by the app's permissions. By putting the special tokens `@@` and/or `@@u` in the Exec field of a Flatpak app's .desktop file, a malicious app publisher can trick flatpak into behaving as though the user had chosen to open a target file with their Flatpak app, which automatically makes that file available to the Flatpak app. This is fixed in version 1.10.2. A minimal solution is the first commit "`Disallow @@ and @@U usage in desktop files`". The follow-up commits "`dir: Reserve the whole @@ prefix`" and "`dir: Refuse to export .desktop files with suspicious uses of @@ tokens`" are recommended, but not strictly required. As a workaround, avoid installing Flatpak apps from untrusted sources, or check the contents of the exported `.desktop` files in `exports/share/applications/*.desktop` (typically `~/.local/share/flatpak/exports/share/applications/*.desktop` and `/var/lib/flatpak/exports/share/applications/*.desktop`) to make sure that literal filenames do not follow `@@` or `@@u`. | ||||
CVE-2021-21261 | 3 Debian, Flatpak, Redhat | 4 Debian Linux, Flatpak, Enterprise Linux and 1 more | 2024-11-21 | 7.3 High |
Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. A bug was discovered in the `flatpak-portal` service that can allow sandboxed applications to execute arbitrary code on the host system (a sandbox escape). This sandbox-escape bug is present in versions from 0.11.4 and before fixed versions 1.8.5 and 1.10.0. The Flatpak portal D-Bus service (`flatpak-portal`, also known by its D-Bus service name `org.freedesktop.portal.Flatpak`) allows apps in a Flatpak sandbox to launch their own subprocesses in a new sandbox instance, either with the same security settings as the caller or with more restrictive security settings. For example, this is used in Flatpak-packaged web browsers such as Chromium to launch subprocesses that will process untrusted web content, and give those subprocesses a more restrictive sandbox than the browser itself. In vulnerable versions, the Flatpak portal service passes caller-specified environment variables to non-sandboxed processes on the host system, and in particular to the `flatpak run` command that is used to launch the new sandbox instance. A malicious or compromised Flatpak app could set environment variables that are trusted by the `flatpak run` command, and use them to execute arbitrary code that is not in a sandbox. As a workaround, this vulnerability can be mitigated by preventing the `flatpak-portal` service from starting, but that mitigation will prevent many Flatpak apps from working correctly. This is fixed in versions 1.8.5 and 1.10.0. | ||||
CVE-2021-20322 | 6 Debian, Fedoraproject, Linux and 3 more | 34 Debian Linux, Fedora, Linux Kernel and 31 more | 2024-11-21 | 7.4 High |
A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. | ||||
CVE-2021-20317 | 3 Debian, Linux, Redhat | 4 Debian Linux, Linux Kernel, Enterprise Linux and 1 more | 2024-11-21 | 4.4 Medium |
A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user privileges to cause a denial of service, slowing and eventually stopping the system while running OSP. | ||||
CVE-2021-20305 | 5 Debian, Fedoraproject, Netapp and 2 more | 10 Debian Linux, Fedora, Active Iq Unified Manager and 7 more | 2024-11-21 | 8.1 High |
A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an invalid signature, causing an assertion failure or possible validation. The highest threat to this vulnerability is to confidentiality, integrity, as well as system availability. | ||||
CVE-2021-20277 | 4 Debian, Fedoraproject, Redhat and 1 more | 8 Debian Linux, Fedora, Enterprise Linux and 5 more | 2024-11-21 | 7.5 High |
A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The highest threat from this vulnerability is to system availability. | ||||
CVE-2021-20271 | 4 Fedoraproject, Redhat, Rpm and 1 more | 9 Fedora, Enterprise Linux, Rhel Aus and 6 more | 2024-11-21 | 7.0 High |
A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is to data integrity, confidentiality, and system availability. | ||||
CVE-2021-20254 | 4 Debian, Fedoraproject, Redhat and 1 more | 9 Debian Linux, Fedora, Enterprise Linux and 6 more | 2024-11-21 | 6.8 Medium |
A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity. | ||||
CVE-2021-20233 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-11-21 | 8.2 High |
A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2021-20230 | 2 Redhat, Stunnel | 3 Enterprise Linux, Rhel Eus, Stunnel | 2024-11-21 | 7.5 High |
A flaw was found in stunnel before 5.57, where it improperly validates client certificates when it is configured to use both redirect and verifyChain options. This flaw allows an attacker with a certificate signed by a Certificate Authority, which is not the one accepted by the stunnel server, to access the tunneled service instead of being redirected to the address specified in the redirect option. The highest threat from this vulnerability is to confidentiality. | ||||
CVE-2021-20225 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-11-21 | 6.7 Medium |
A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2021-20188 | 2 Podman Project, Redhat | 5 Podman, Enterprise Linux, Openshift Container Platform and 2 more | 2024-11-21 | 7.0 High |
A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2021-20179 | 3 Dogtagpki, Fedoraproject, Redhat | 5 Dogtagpki, Fedora, Certificate System and 2 more | 2024-11-21 | 8.1 High |
A flaw was found in pki-core. An attacker who has successfully compromised a key could use this flaw to renew the corresponding certificate over and over again, as long as it is not explicitly revoked. The highest threat from this vulnerability is to data confidentiality and integrity. | ||||
CVE-2021-1998 | 4 Fedoraproject, Netapp, Oracle and 1 more | 10 Fedora, Active Iq Unified Manager, Oncommand Insight and 7 more | 2024-11-21 | 3.8 Low |
