------------------------------------------------------------------------- Debian LTS Advisory DLA-3145-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Markus Koschany October 11, 2022 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : git Version : 1:2.20.1-2+deb10u4 CVE ID : CVE-2021-21300 CVE-2021-40330 Debian Bug : 985120 Several security vulnerabilities have been discovered in Git, a fast, scalable, distributed revision control system, which may affect multi-user systems. CVE-2021-21300 A specially crafted repository that contains symbolic links as well as files using a clean/smudge filter such as Git LFS, may cause just-checked out script to be executed while cloning onto a case-insensitive file system such as NTFS, HFS+ or APFS (i.e. the default file systems on Windows and macOS). CVE-2021-40330 git_connect_git in connect.c allows a repository path to contain a newline character, which may result in unexpected cross-protocol requests, as demonstrated by the git://localhost:1234/%0d%0a%0d%0aGET%20/%20HTTP/1.1 substring. For Debian 10 buster, these problems have been fixed in version 1:2.20.1-2+deb10u4. We recommend that you upgrade your git packages.
