The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges. La implementación de overlayfs en el kernel de Linux no comprobó apropiadamente con respecto a los espacios de nombre de los usuarios, la configuración de las capacidades de los archivos en un sistema de archivos subyacente. Debido a la combinación de los espacios de nombre de usuarios no privilegiados junto con un parche incluido en el kernel de Ubuntu para permitir montajes de superposición no privilegiados, un atacante podría usar esto para alcanzar privilegios elevados The overlayfs stacking file system in Linux kernel does not properly validate the application of file capabilities against user namespaces, which could lead to privilege escalation. • https://github.com/briskets/CVE-2021-3493 https://github.com/inspiringz/CVE-2021-3493 https://github.com/oneoy/CVE-2021-3493 https://github.com/cerodah/overlayFS-CVE-2021-3493 https://github.com/derek-turing/CVE-2021-3493 https://github.com/puckiestyle/CVE-2021-3493 https://github.com/smallkill/CVE-2021-3493 https://github.com/Abdennour-py/CVE-2021-3493 https://github.com/fei9747/CVE-2021-3493 https://github.com/ptkhai15/OverlayFS---CVE-2021-3493 https://git • CWE-270: Privilege Context Switching Error CWE-863: Incorrect Authorization •

Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copy_from_user() correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service (kernel memory exhaustion) or gain privileges via executing arbitrary code. AKA ZDI-CAN-13562. Shiftfs, un sistema de archivos de apilamiento fuera del árbol incluido en los kernels de Ubuntu Linux, no manejaba apropiadamente los fallos que ocurrían durante la función copy_from_user(). • https://github.com/synacktiv/CVE-2021-3492 http://packetstormsecurity.com/files/162614/Kernel-Live-Patch-Security-Notice-LSN-0077-1.html https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal/commit/?id=25c891a949bf918b59cbc6e4932015ba4c35c333 https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal/commit/?id=8fee52ab9da87d82bc6de9ebb3480fff9b4d53e6 https://ubuntu.com/security/notices/USN-4917-1 https://www.openwall.com/lists/oss-security/2021/04/16/2 https:&#x • CWE-401: Missing Release of Memory after Effective Lifetime CWE-415: Double Free •

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Client programs). Supported versions that are affected are 5.5.59 and prior, 5.6.39 and prior and 5.7.21 and prior. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.
