Synopsis:	Important: glibc security update
Issue date:	2010-10-25
CVE Names:	CVE-2010-3856

It was discovered that the glibc dynamic linker/loader did not perform
sufficient safety checks when loading dynamic shared objects (DSOs) to
provide callbacks for its auditing API during the execution of
privileged programs. A local attacker could use this flaw to escalate
their privileges via a carefully-chosen system DSO library containing
unsafe constructors. (CVE-2010-3856)
