A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. Se ha encontrado una vulnerabilidad en la función cgroup_release_agent_write en el archivo kernel/cgroup/cgroup-v1.c del kernel de Linux. Este fallo, bajo determinadas circunstancias, permite el uso de la función cgroups v1 release_agent para escalar privilegios y saltarse el aislamiento del espacio de nombres de forma no esperada • https://github.com/chenaotian/CVE-2022-0492 https://github.com/SofianeHamlaoui/CVE-2022-0492-Checker https://github.com/yoeelingBin/CVE-2022-0492-Container-Escape https://github.com/T1erno/CVE-2022-0492-Docker-Breakout-Checker-and-PoC https://github.com/bb33bb/CVE-2022-0492 http://packetstormsecurity.com/files/166444/Kernel-Live-Patch-Security-Notice-LSN-0085-1.html http://packetstormsecurity.com/files/167386/Kernel-Live-Patch-Security-Notice-LSN-0086-1.html http://packetstormsecurity.com/files/17 • CWE-287: Improper Authentication CWE-862: Missing Authorization •

A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network. Se ha encontrado un fallo de desbordamiento de pila en la funcionalidad del protocolo TIPC del kernel de Linux en la forma en que un usuario envía un paquete con contenido malicioso cuando el número de nodos miembros del dominio es superior a los 64 permitidos.

The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. El módulo vfs_fruit de Samba usa atributos de archivo extendidos (EA, xattr) para proporcionar "...compatibilidad mejorada con los clientes SMB de Apple e interoperabilidad con un servidor de archivos AFP de Netatalk 3". Samba versiones anteriores a 4.13.17, 4.14.12 y 4.15.5 con vfs_fruit configurado permiten una lectura y escritura fuera de límites de la pila por medio de atributos de archivo extendidos especialmente diseñados. • https://github.com/horizon3ai/CVE-2021-44142 https://github.com/gudyrmik/CVE-2021-44142 https://github.com/hrsman/Samba-CVE-2021-44142 https://bugzilla.samba.org/show_bug.cgi?id=14914 https://kb.cert.org/vuls/id/119678 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2021-44142.html https://www.zerodayinitiative.com/blog/2022/2/1/cve-2021-44142-details-on-a-samba-code-execution-bug-demonstrated-at-pwn2own-austin https://access.redhat&# • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
