"This update of glibc fixes two bugs and security issues :

CVE-2010-3847: Decoding of the $ORIGIN special value in various LD_
environment variables allowed local attackers to execute code in
context of e.g. setuid root programs, elevating privileges. This issue
does not affect SUSE as an assertion triggers before the respective
code is executed. The bug was fixed nevertheless.

CVE-2010-3856: The LD_AUDIT environment was not pruned during setuid
root execution and could load shared libraries from standard system
library paths. This could be used by local attackers to inject code
into setuid root programs and so elevated privileges."
