CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-29468 – Arbitrary code execution when checking out an attacker-controlled Git branch
https://notcve.org/view.php?id=CVE-2021-29468
Cygwin Git is a patch set for the git command line tool for the cygwin environment. A specially crafted repository that contains symbolic links as well as files with backslash characters in the file name may cause just-checked out code to be executed while checking out a repository using Git on Cygwin. The problem will be patched in the Cygwin Git v2.31.1-2 release. At time of writing, the vulnerability is present in the upstream Git source code; any Cygwin user who compiles Git for themselves from upstream sources should manually apply a patch to mitigate the vulnerability. As mitigation users should not clone or pull from repositories from untrusted sources. • https://cygwin.com/pipermail/cygwin-announce/2021-April/010018.html https://github.com/me-and/Cygwin-Git/blob/main/check-backslash-safety.patch https://github.com/me-and/Cygwin-Git/security/advisories/GHSA-rmp3-wq55-f557 https://lore.kernel.org/git/CA+kUOa=juEdBMVr_gyTKjz7PkPt2DZHkXQyzcQmAWCsEHC_ssw%40mail.gmail.com/T/#u • CWE-20: Improper Input Validation •

Cygwin versions 1.7.2 up to and including 1.8.0 are vulnerable to buffer overflow vulnerability in wcsxfrm/wcsxfrm_l functions resulting into denial-of-service by crashing the process or potential hijack of the process running with administrative privileges triggered by specially crafted input string. Cygwin versiones 1.7.2 hasta e incluyendo a 1.8.0, son susceptibles a una vulnerabilidad de desbordamiento de búfer en las funciones wcsxfrm y wcsxfrm_l resultando en una denegación de servicio por el bloqueo o el posible secuestro del proceso que se ejecuta con privilegios administrativos activado por una cadena de entrada especialmente creada. • https://cygwin.com/ml/cygwin/2017-05/msg00149.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

Cygwin before 2.5.0 does not properly handle updating permissions when changing users, which allows attackers to gain privileges. Cygwin en versiones anteriores a 2.5.0 no maneja adecuadamente la actualización de permisos al cambiar de usuario, lo que permite a los atacantes obtener privilegios. • https://cygwin.com/ml/cygwin-announce/2016-02/msg00023.html https://cygwin.com/ml/cygwin-announce/2016-04/msg00020.html https://cygwin.com/ml/cygwin-announce/2016-04/msg00054.html https://cygwin.com/ml/cygwin/2016-02/msg00129.html https://sourceware.org/git/?p=newlib-cygwin.git%3Ba=commit%3Bh=205862ed08649df8f50b926a2c58c963f571b044 • CWE-264: Permissions, Privileges, and Access Controls •
