CVE-2021-3696 3 Gnu, Netapp, Redhat 15 Grub2, Ontap Select Deploy Administration Utility, Codeready Linux Builder and 12 more 2024-11-21 4.5 Medium
A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3695 4 Fedoraproject, Gnu, Netapp and 1 more 16 Fedora, Grub2, Ontap Select Deploy Administration Utility and 13 more 2024-11-21 4.5 Medium
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3672 6 C-ares Project, Fedoraproject, Nodejs and 3 more 19 C-ares, Fedora, Node.js and 16 more 2024-11-21 5.6 Medium
A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability.
CVE-2021-3656 3 Fedoraproject, Linux, Redhat 31 Fedora, Linux Kernel, 3scale Api Management and 28 more 2024-11-21 8.8 High
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape.
CVE-2021-3653 3 Debian, Linux, Redhat 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more 2024-11-21 8.8 High
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to 5.14-rc7.
CVE-2021-3652 2 Port389, Redhat 4 389-ds-base, Directory Server, Enterprise Linux and 1 more 2024-11-21 6.5 Medium
A flaw was found in 389-ds-base. If an asterisk is imported as password hashes, either accidentally or maliciously, then instead of being inactive, any password will successfully match during authentication. This flaw allows an attacker to successfully authenticate as a user whose password was disabled.
CVE-2021-3640 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2024-11-21 7.0 High
A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.
CVE-2021-3621 2 Fedoraproject, Redhat 10 Fedora, Sssd, Enterprise Linux and 7 more 2024-11-21 8.8 High
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3609 3 Linux, Netapp, Redhat 46 Linux Kernel, H300e, H300e Firmware and 43 more 2024-11-21 7.0 High
.A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.
CVE-2021-3570 4 Debian, Fedoraproject, Linuxptp Project and 1 more 8 Debian Linux, Fedora, Linuxptp and 5 more 2024-11-21 8.8 High
A flaw was found in the ptp4l program of the linuxptp package. A missing length check when forwarding a PTP message between ports allows a remote attacker to cause an information leak, crash, or potentially remote code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. This flaw affects linuxptp versions before 3.1.1, before 2.0.1, before 1.9.3, before 1.8.1, before 1.7.1, before 1.6.1 and before 1.5.1.
CVE-2021-3521 2 Redhat, Rpm 3 Enterprise Linux, Rhel Eus, Rpm 2024-11-21 4.7 Medium
There is a flaw in RPM's signature functionality. OpenPGP subkeys are associated with a primary key via a "binding signature." RPM does not check the binding signature of subkeys prior to importing them. If an attacker is able to add or socially engineer another party to add a malicious subkey to a legitimate public key, RPM could wrongly trust a malicious signature. The greatest impact of this flaw is to data integrity. To exploit this flaw, an attacker must either compromise an RPM repository or convince an administrator to install an untrusted RPM or public key. It is strongly recommended to only use RPMs and public keys from trusted sources.
CVE-2021-3514 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2024-11-21 6.5 Medium
When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer dereference using a specially crafted query, causing a crash.
CVE-2021-3480 3 Fedoraproject, Redhat, Slapi-nis Project 4 Fedora, Enterprise Linux, Rhel Eus and 1 more 2024-11-21 7.5 High
A flaw was found in slapi-nis in versions before 0.56.7. A NULL pointer dereference during the parsing of the Binding DN could allow an unauthenticated attacker to crash the 389-ds-base directory server. The highest threat from this vulnerability is to system availability.
CVE-2021-3449 13 Checkpoint, Debian, Fedoraproject and 10 more 172 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 169 more 2024-11-21 5.9 Medium
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).
CVE-2021-3421 3 Fedoraproject, Redhat, Rpm 4 Fedora, Enterprise Linux, Rhel Eus and 1 more 2024-11-21 5.5 Medium
A flaw was found in the RPM package in the read functionality. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package or compromise an RPM repository, to cause RPM database corruption. The highest threat from this vulnerability is to data integrity. This flaw affects RPM versions before 4.17.0-alpha.
CVE-2021-3393 2 Postgresql, Redhat 5 Postgresql, Enterprise Linux, Rhel Eus and 2 more 2024-11-21 4.3 Medium
