Guillem Jover discovered that the changelog retrieval functionality in apt-get used temporary files in an insecure way, allowing a local user to cause arbitrary files to be overwritten. This vulnerability is neutralized by the fs.protected_symlinks setting in the Linux kernel, which is enabled by default in Debian 7 Wheezy and up.

For the stable distribution (wheezy), this problem has been fixed in version 0.9.7.9+deb7u6. For the unstable distribution (sid), this problem has been fixed in version 1.0.9.2. We recommend that you upgrade your apt packages.

This package provides commandline tools for searching and managing as well as querying information about packages as a low-level access to all features of the libapt-pkg library.
