Synopsis: Moderate: libarchive security update
Issue Date: 2011-12-01
CVE Numbers: CVE-2010-4666

The libarchive programming library can create and read several different
streaming archive formats, including GNU tar and cpio. It can also read ISO
9660 CD-ROM images.

Two heap-based buffer overflow flaws were discovered in libarchive. If a
user were tricked into expanding a specially-crafted ISO 9660 CD-ROM image
or tar archive with an application using libarchive, it could cause the
application to crash or, potentially, execute arbitrary code with the
privileges of the user running the application. (CVE-2011-1777,
CVE-2011-1778)

All libarchive users should upgrade to these updated packages, which
contain backported patches to correct these issues. All running
applications using libarchive must be restarted for this update to take
effect.
