Package : libtar
Vulnerability : directory traversal
CVE ID : CVE-2013-4420
Debian Bug : 731860
A directory traversal attack was reported against libtar, a C library for manipulating tar archives. The application does not validate the
filenames inside the tar archive, allowing to extract files in arbitrary
path. An attacker can craft a tar file to override files beyond the tar_extract_glob and tar_extract_all prefix parameter.
For the oldstable distribution (squeeze), this problem has been fixed in version 1.2.11-6+deb6u2.
For the stable distribution (wheezy), this problem has been fixed in
version 1.2.16-1+deb7u2.
For the unstable distribution (sid), this problem has been fixed in
version 1.2.20-2.
We recommend that you upgrade your libtar packages.
