"Updated rpm packages that fix two security issues are now available
for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The RPM Package Manager (RPM) is a command line driven package
management system capable of installing, uninstalling, verifying,
querying, and updating software packages.

It was discovered that RPM did not remove setuid and setgid bits set
on binaries when upgrading or removing packages. A local attacker able
to create hard links to binaries could use this flaw to keep those
binaries on the system, at a specific version level and with the
setuid or setgid bit set, even if the package providing them was
upgraded or removed by a system administrator. This could have
security implications if a package was upgraded or removed because of
a security flaw in a setuid or setgid program. (CVE-2005-4889,
CVE-2010-2059)

All users of rpm are advised to upgrade to these updated packages,
which contain a backported patch to correct these issues."
