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 up[censored] 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"
