14 Dec 2021 — JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in Au... • https://github.com/cckuailong/log4shell_1.x • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •

27 Aug 2021 — squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination. La función squashfs_opendir en el archivo unsquash-1.c en Squashfs-Tools versión 4.5, almacena el nombre del archivo en la entrada del directorio; esto es entonces usado por unsquashfs para ... • https://bugs.launchpad.net/ubuntu/+source/squashfs-tools/+bug/1941790 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

11 Mar 2021 — A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver software. The impact of this issue is lessened by the fact that the default permissions on the floppy device (/dev/fd0) are restricted to root. If the permissions on the device have changed the impact changes greatly. In the default configuration root (or equivalent) permissions are required to attack this flaw.

23 Feb 2021 — There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y , CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution, the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly privileges esc... • https://bugzilla.redhat.com/show_bug.cgi?id=1912683 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •

15 Jan 2021 — A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC. This flaw allows a local user to crash the system. Se encontró un fallo de desreferencia del puntero NULL en la funcionalidad del controlador GPU Nouveau del kernel de Linux en versiones anteriores a 5.12-rc1, en la manera en que el usuario llama a ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC.

11 Dec 2020 — A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

05 Dec 2020 — A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries platform) a root like local user could use this flaw to further increase their privileges to that of a running kernel.
