Subject: Updated glibc package for SOT Linux 2003
Advisory ID: SLSA-2003:52
Date: Sunday, November 16, 2003
Product: OT Linux 2003

1. Problem description

The glibc packages contain GNU libc, which provides standard system libraries.

The getgrouplist function in GNU libc allows may attackers to cause a denial of service (segmentation fault) and execute arbitrary code when a user is a member of a large number of groups, which can cause a buffer overflow. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0689 to this issue.

SOT Linux 2003 users are advised to update glibc package.
