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:

Upstream changeset:

Could you allocate CVE id for this?

Thanks && Regards, Jan.
