Synopsis
========

Multiple vulnerabilities have been found in RPM, possibly allowing
local attackers to gain elevated privileges or remote attackers to
execute arbitrary code.

Background
==========

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

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-arch/rpm                < 4.9.1.3                 >= 4.9.1.3

Description
===========

Multiple vulnerabilities have been found in RPM:

* fsm.c fails to properly strip setuid and setgid bits from executable
  files during a package upgrade (CVE-2010-2059).
* RPM does not properly parse spec files (CVE-2010-2197).
* fsm.c fails to properly strip POSIX file capabilities from executable
  files during a package upgrade or removal (CVE-2010-2198).
* fsm.c fails to properly strip POSIX ACLs from executable files during
  a package upgrade or removal (CVE-2010-2199).
* header.c does not properly parse region offsets in package files
  (CVE-2011-3378).
* RPM does not properly sanitize region tags in package headers
  (CVE-2012-0060).
* RPM does not properly sanitize region sizes in package headers
  (CVE-2012-0061).
* RPM does not properly sanitize region offsets in package
  headers(CVE-2012-0815).

Impact
======

A local attacker may be able to gain elevated privileges. Furthermore,
a remote attacker could entice a user to open a specially crafted RPM
package, possibly resulting in execution of arbitrary code with the
privileges of the process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All RPM users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-arch/rpm-4.9.1.3"
