[slackware-security]  glibc XDR overflow fix (SSA:2003-141-03)

An integer overflow in the xdrmem_getbytes() function found in the glibc
library has been fixed.  This could allow a remote attacker to execute
arbitrary code by exploiting RPC service that use xdrmem_getbytes().  None of
the default RPC services provided by Slackware  appear to use this function,
but third-party applications may make use of it.

We recommend upgrading to these new glibc packages.


Here are the details from the Slackware 9.0 ChangeLog:
+--------------------------+
Tue May 20 20:13:09 PDT 2003
patches/packages/glibc-2.3.1-i386-4.tgz:  Patched, recompiled.

patches/packages/glibc-solibs-2.3.1-i386-4.tgz:  Patched a buffer overflow in
  some dead code (xdrmem_getbytes(), which we couldn't find used by anything,
  but it doesn't hurt to patch it anyway)
