Synopsis
Important: rpm security update
Type/Severity
Security Advisory: Important
Topic
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.
Description
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.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
