| CVE-2021-41133 | 4 Debian, Fedoraproject, Flatpak and 1 more | 5 Debian Linux, Fedora, Flatpak and 2 more | 2024-11-21 | 8.8 High |
| Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In versions prior to 1.10.4 and 1.12.0, Flatpak apps with direct access to AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can trick portals and other host-OS services into treating the Flatpak app as though it was an ordinary, non-sandboxed host-OS process. They can do this by manipulating the VFS using recent mount-related syscalls that are not blocked by Flatpak's denylist seccomp filter, in order to substitute a crafted `/.flatpak-info` or make that file disappear entirely. Flatpak apps that act as clients for AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can escalate the privileges that the corresponding services will believe the Flatpak app has. Note that protocols that operate entirely over the D-Bus session bus (user bus), system bus or accessibility bus are not affected by this. This is due to the use of a proxy process `xdg-dbus-proxy`, whose VFS cannot be manipulated by the Flatpak app, when interacting with these buses. Patches exist for versions 1.10.4 and 1.12.0, and as of time of publication, a patch for version 1.8.2 is being planned. There are no workarounds aside from upgrading to a patched version. | ||||
| CVE-2021-41099 | 6 Debian, Fedoraproject, Netapp and 3 more | 10 Debian Linux, Fedora, Management Services For Element Software And Netapp Hci and 7 more | 2024-11-21 | 7.5 High |
| Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the underlying string library can be used to corrupt the heap and potentially result with denial of service or remote code execution. The vulnerability involves changing the default proto-max-bulk-len configuration parameter to a very large value and constructing specially crafted network payloads or commands. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command. | ||||

| CVE-2021-3750 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Rhel Eus | 2024-11-21 | 8.2 High |
| A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects QEMU versions before 7.0.0. | ||||
| CVE-2021-3715 | 2 Linux, Redhat | 5 Linux Kernel, Enterprise Linux, Rhel E4s and 2 more | 2024-11-21 | 7.8 High |
| A flaw was found in the "Routing decision" classifier in the Linux kernel's Traffic Control networking subsystem in the way it handled changing of classification filters, leading to a use-after-free condition. This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | ||||
| CVE-2021-3697 | 2 Gnu, Redhat | 14 Grub2, Codeready Linux Builder, Developer Tools and 11 more | 2024-11-21 | 7.0 High |
| A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. | ||||
| 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 |
