Package: rpm
Version: 4.7.2-1+b2
Severity: important
Hi,
the following security issue was reported on the oss-security mailing
list. We don't need to fix this in stable, but a fix for Squeeze might
still be appropriate.
Cheers,

Subject: [oss-security] 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.

Could you allocate CVE id for this?
Thanks && Regards, Jan.
