Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2003:334

The remote host is missing updates announced in
advisory RHSA-2003:334.

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 ( has
assigned the name CVE-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.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
