CentOS Errata and Security Advisory CESA-2012:0451

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

Multiple flaws were found in the way RPM parsed package file headers. An
attacker could create a specially-crafted RPM package that, when its
package header was accessed, or during package signature verification,
could cause an application using the RPM library (such as the rpm command
line tool, or the yum and up2date package managers) to crash or,
potentially, execute arbitrary code. (CVE-2012-0060, CVE-2012-0061,
CVE-2012-0815)

Note: Although an RPM package can, by design, execute arbitrary code when
installed, this issue would allow a specially-crafted RPM package to
execute arbitrary code before its digital signature has been verified.
Package downloads from the Red Hat Network are protected by the use of a
secure HTTPS connection in addition to the RPM package signature checks.

All RPM users should upgrade to these updated packages, which contain a
backported patch to correct these issues. All running applications linked
against the RPM library must be restarted for this update to take effect.
