William Grant discovered that dpkg-source did not safely apply diffs when unpacking source packages. If a user or an automated system were tricked into unpacking a specially crafted source package, a remote attacker could modify files outside the target unpack directory, leading to a denial of service or potentially gaining access to the system.

William Grant discovered that the dpkg-source component of dpkg, the low-level infrastructure for handling the installation and removal of Debian software packages, is vulnerable to path traversal attacks. A specially crafted Debian source package can lead to file modification outside of the destination directory when extracting the package content.
