Packages
- dpkg - Debian package management system
Details
Jakub Wilk and Raphael Hertzog discovered that dpkg-source did not
correctly handle certain paths and symlinks when unpacking source-format
version 3.0 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.
