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 August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. • http://www.openwall.com/lists/oss-security/2022/01/18/3 https://access.redhat.com/security/cve/CVE-2021-4104 https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126 https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2021-0033 https://security.gentoo.org/glsa/202209-02 https://security.gentoo.org/glsa/202310-16 https://security.gentoo.org/glsa/202312-02 https://security.gentoo.org/glsa/202312-04 https://security.netapp.com/advisory/ntap-20211223-0007 https&# • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •

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 crear el nuevo archivo durante el desensamblaje. El nombre de archivo no se comprueba para saltar fuera del directorio de destino, y por lo tanto permite escribir en lugares fuera del destino. A flaw was found in Squashfs-tools, where it is vulnerable to attacks similar to zip-slip. • https://bugs.launchpad.net/ubuntu/+source/squashfs-tools/+bug/1941790 https://github.com/plougher/squashfs-tools/commit/79b5a555058eef4e1e7ff220c344d39f8cd09646 https://github.com/plougher/squashfs-tools/issues/72 https://lists.debian.org/debian-lts-announce/2021/08/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GSMRKVJMJFX3MB7D3PXJSYY3TLZROE5S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RAOZ4BKWAC4Y3U2K5MMW3S77HWWXHQDL https:&# • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

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. Se encontró una condición de carrera en la implementación del kernel de Linux del software manejador del controlador de la unidad de disquete. • https://bugzilla.redhat.com/show_bug.cgi?id=1932150 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a0c80efe5956ccce9fe7ae5c78542578c07bc20a • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

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.

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 escalation. Se presenta una vulnerabilidad en el kernel de Linux versiones superiores a 5.2 (si el kernel compilado con los parámetros config CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y , CONFIG_HARDENED_USERCOPY no se establece y el hook BPF a getsockopt está registrado). Como resultado de la ejecución de BPF, el usuario local puede desencadenar un error en la función __cgroup_bpf_run_filter_getsockopt() que puede conllevar a un desbordamiento de la pila (debido a una copia de usuario no reforzada). • https://bugzilla.redhat.com/show_bug.cgi?id=1912683 https://security.netapp.com/advisory/ntap-20210326-0003 https://access.redhat.com/security/cve/CVE-2021-20194 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
