112434 : RHSA-2003-334: Glibc

Risk 3 : Red Hat Local Checks

Updated glibc packages that resolve a vulnerability and address several bugs are now available.

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

Herbert Xu reported that various applications can accept spoofed messages sent on the kernel netlink interface by other users on the local machine. This could lead to a local denial of service attack. The glibc function getifaddrs uses netlink and could therefore be vulnerable to this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0859 to this issue.

In addition to the security issues, a number of other bugs were fixed.

Users are advised to upgrade to these erratum packages, which contain a patch that checks that netlink messages actually came from the kernel and patches for the various bug fixes.
