gnupg security update (RHSA-2006-0571)

Original Release Date: August 18, 2006
Last Revised: December 5, 2007
Number: ASA-2006-167
Risk Level: Medium
Advisory Version: 3.0
Advisory Status: Final

1. Overview:

GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC2440

The GNU Privacy Guard (GPG) was found to contain an integer overflow flaw as a result of handling large packet sizes. Using a specially crafted message, a malicious user could cause GPG to crash and/or overwrite space in memory when processing the large packets. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-3082 to this issue.

The Avaya S87XX/S8500/S8300 Media Gateway products are listed with a Medium risk impact as GPG is called by backup scripts that can be called with elevated privileges via the sudo command.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:

3. Avaya Software-Only Products

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendors guidance:
