Description
CVE-2026-91094 is a directory traversal vulnerability in the Debian dpkg tool when unpacking 3.0 (quilt) source packages. The issue arises because the packaging tarball can include the quilt database directory (.pc) containing attacker-controlled symbolic links. When patches fail to apply, the code that restores backup files may follow these symlinks, allowing modification or removal of arbitrary files pointed to by the attacker.
