Oracle Linux 4 / 5 / 6 : rpm (ELSA-2012-0451)

Description

From Red Hat Security Advisory 2012:0451 : Updated rpm packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6; Red Hat Enterprise Linux 3 and 4 Extended Life Cycle Support; Red Hat Enterprise Linux 5.3 Long Life; and Red Hat Enterprise Linux 5.6, 6.0 and 6.1 Extended Update Support. The Red Hat Security Response Team has rated this update as having important 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. 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.
