SOT Linux Security Advisory
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.
