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. For the stable distribution , this problem has been fixed in version 1.14.29. For the testing and unstable distribution this problem will be fixed soon. We recommend that you upgrade your dpkg packages.
