Directory traversal vulnerability in dpkg-source in dpkg before 1.14.31 and 1.15.x allows user-assisted remote attackers to modify arbitrary files via directory traversal sequences in a patch for a source-format 3.0 package.

The remote Solaris system is missing necessary patches to address security updates :

  - Directory traversal vulnerability in dpkg-source in dpkg     before 1.14.31 and 1.15.x allows user-assisted remote     attackers to modify arbitrary files via directory     traversal sequences in a patch for a source-format 3.0     package. (CVE-2010-1679)

  - Directory traversal vulnerability in util.c in GNU patch     2.6.1 and earlier allows user-assisted remote attackers     to create or overwrite arbitrary files via a filename     that is specified with a .. (dot dot) or full pathname,     a related issue to CVE-2010-1679. (CVE-2010-4651)

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.

Jakub Wilk discovered that the dpkg-source component of dpkg, the Debian package management system, doesn't correctly handle paths in patches of source packages, which could make it traverse directories.
Raphael Hertzog additionally discovered that symbolic links in the .pc directory are followed, which could make it traverse directories too.

Both issues only affect source packages using the '3.0 quilt' format at unpack-time.
