CVE-2021-3156 – Sudo Heap-Based Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2021-3156
Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character. Sudo versiones anteriores a 1.9.5p2 contiene un error de desbordamiento que puede resultar en un desbordamiento de búfer basado en la pila, lo que permite la escalada de privilegios a root a través de "sudoedit -s" y un argumento de línea de comandos que termina con un solo carácter de barra invertida A flaw was found in sudo. A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is exploitable by any local user who can execute the sudo command (by default, any local user can execute sudo) without authentication. Successful exploitation of this flaw could lead to privilege escalation. • https://www.exploit-db.com/exploits/49521 https://www.exploit-db.com/exploits/49522 https://github.com/blasty/CVE-2021-3156 https://github.com/worawit/CVE-2021-3156 https://github.com/stong/CVE-2021-3156 https://github.com/reverse-ex/CVE-2021-3156 https://github.com/CptGibbon/CVE-2021-3156 https://github.com/Rvn0xsy/CVE-2021-3156-plus https://github.com/mr-r3b00t/CVE-2021-3156 https://github.com/0xdevil/CVE-2021-3156 https://github.com/unauth401/CVE-20 • CWE-122: Heap-based Buffer Overflow CWE-193: Off-by-one Error •
CVE-2021-23239 – sudo: possible directory existence test due to race condition in sudoedit
https://notcve.org/view.php?id=CVE-2021-23239
The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path. La personalidad sudoedit de Sudo versiones anteriores a 1.9.5, puede permitir a un usuario local poco privilegiado llevar a cabo pruebas arbitrarias de existencia de directorio al ganar una condición de carrera en el archivo sudo_edit.c al reemplazar un directorio controlado por el usuario por un enlace simbólico a una ruta arbitraria A flaw was found in sudoedit. A race condition vulnerability and improper symbolic link resolution could be used by a local unprivileged user to test for the existence of directories and files not normally accessible to the user. This flaw cannot be used to read the content or write to arbitrary files on the file system. The highest threat from this vulnerability is to data confidentiality. • https://bugzilla.suse.com/show_bug.cgi?id=CVE-2021-23239 https://lists.debian.org/debian-lts-announce/2022/11/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EE42Y35SMJOLONAIBNYNFC7J44UUZ2Y6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GMY4VSSBIND7VAYSN6T7XIWJRWG4GBB3 https://security.gentoo.org/glsa/202101-33 https://security.netapp.com/advisory/ntap-20210129-0010 https://www.sudo.ws/stable.html#1.9.5 h • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-203: Observable Discrepancy •
