Subject: CVE Request -- rpm -- Fails to remove the SUID/SGID bits on package
 upgrade (RH BZ#598775)

Hi Steve, vendors,

    Matt McCutchen pointed out a deficiency in the way rpm handled rpm package upgrades --
it failed to clear out the SUID/SGID bits of the old file by file replacement when privileged
user performed package upgrade. Under certain circumstances, a local, authenticated user could
use this flaw to escalate their privileges.

Red Hat Bugzilla entry:
   [1] https://bugzilla.redhat.com/show_bug.cgi?id=598775

Upstream changeset:
   [2] http://rpm.org/gitweb?p=rpm.git;a=commit;h=ca2d6b2b484f1501eafdde02e1688409340d2383

Could you allocate CVE id for this?

Thanks && Regards, Jan.
