RHEL 6 : libarchive (RHSA-2011:1507)

high Nessus Plugin ID 56990

Synopsis

The remote Red Hat host is missing one or more security updates for libarchive.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1507 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL libarchive package based on the guidance in RHSA-2011:1507.
