libgit2: libgit2: Denial of Service due to heap out-of-bounds read from malicious Git server

A flaw was found in libgit2. A fixed-size string comparison in the setdata function within transports/smartpkt.c does not adequately verify the size of a network packet buffer. A remote attacker, operating a malicious Git server, can send a specially crafted packet-line capability buffer. This ca...

DEBIAN-CVE-2026-78677

GitPython before 3.1.59 omits --separate-git-dir from unsafegitcloneoptions, allowing attackers to create arbitrary git directories outside the intended clone destination. Attackers can pass a separategitdir parameter to Repo.clonefrom or Repo.clone to redirect repository metadata to an...

CVE-2026-78676

GitPython before 3.1.59 fails to safely re-serialize multi-line git-config values during write operations, corrupting dormant quoted values into injected directives like core.hooksPath. Attackers can craft config files with embedded newlines that become live git directives after any unrelated...
