RHEL 2.1 : glibc (RHSA-2003:090)

High Nessus Plugin ID 12377


The remote Red Hat host is missing one or more security updates.


Updated glibc packages are available to fix an integer overflow in the XDR decoder.

The glibc package contains standard libraries which are used by multiple programs on the system. Sun RPC is a remote procedure call framework which allows clients to invoke procedures in a server process over a network. XDR is a mechanism for encoding data structures for use with RPC. NFS, NIS, and many other network services are built upon Sun RPC. The XDR encoder/decoder provided with glibc, derived from Sun's RPC implementation, was demonstrated to be vulnerable to an integer overflow.

An integer overflow is present in the xdrmem_getbytes() function of glibc 2.3.1 and earlier. Depending upon the application, this vulnerability could cause buffer overflows and may be exploitable, leading to arbitrary code execution.

All users should upgrade to these errata packages which contain patches to the glibc libraries and, therefore, are not vulnerable to these issues.

Red Hat would like to thank eEye Digital Security for alerting us to this issue.


Update the affected packages.
