Vulnerability Assessment Details

RHSA-2003-090: glibc

Vulnerability Assessment Summary
Check for the version of the glibc packages

Detailed Explanation for this Vulnerability Assessment

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 permits 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.
