https://notcve.org/view.php?id=CVE-2022-0492
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 use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se ha encontrado un fallo de uso de memoria previamente liberada en el subsistema Bluetooth del kernel de Linux en la forma en que las llamadas de usuario son conectadas al socket y son desconectadas simultáneamente debido a una condición de carrera.

https://notcve.org/view.php?id=CVE-2021-44142
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 •

CVSS: 8.2EPSS: 31%CPEs: 37EXPL: 0CVE-2021-44224 – Possible NULL dereference or SSRF in forward proxy configurations in Apache HTTP Server 2.4.51 and earlier
https://notcve.org/view.php?id=CVE-2021-44224
A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). Un URI diseñado que es enviado a httpd configurado como proxy directo (ProxyRequests on) puede causar un fallo (desreferencia de puntero NULL) o, en el caso de configuraciones que mezclan declaraciones de proxy directo e inverso, puede permitir que las peticiones se dirijan a un endpoint de socket de dominio Unix declarado (Server Side Request Forgery). Este problema afecta a Apache HTTP Server versiones 2.4.7 hasta 2.4.51 (incluyéndola) There's a null pointer dereference and server-side request forgery flaw in httpd's mod_proxy module, when it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket requests. • http://httpd.apache.org/security/vulnerabilities_24.html http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2021/12/20/3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BFSWOH4X77CV7AH7C4RMHUBDWKQDL4YH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RGWILBORT67SHMSLYSQZG2NMXGCMPUZO https:// • CWE-476: NULL Pointer Dereference CWE-918: Server-Side Request Forgery (SSRF) •
