Red Hat: RHSA-2011:1507-01 Moderate: Libarchive Buffer Overflow

red hat
Calendar Grey December 1, 2011
Dist Redhat Esm H88
Recent libarchive updates for Red Hat Enterprise Linux address several moderate security vulnerabilities and provide comprehensive severity assessments.
Updated libarchive packages that fix two security issues are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

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.
