Red Hat Security Advisory

 

Synopsis: Moderate: apr-util security update

Advisory ID: RHSA-2009:1107-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1107.html

Issue date: 2009-06-16

CVE Names: CVE-2009-0023 CVE-2009-1955 CVE-2009-1956

=====================================================================

 

1. Summary:

 

Updated apr-util packages that fix multiple security issues are now

available for Red Hat Enterprise Linux 4 and 5.

 

This update has been rated as having moderate security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64

Red Hat Enterprise Linux Desktop version 4 - i386, x86_64

Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64

Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

RHEL Desktop Workstation (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

 

3. Description:

 

apr-util is a utility library used with the Apache Portable Runtime (APR).

It aims to provide a free library of C data structures and routines. This

library contains additional utility interfaces for APR; including support

for XML, LDAP, database interfaces, URI parsing, and more.

 

An off-by-one overflow flaw was found in the way apr-util processed a

variable list of arguments. An attacker could provide a specially-crafted

string as input for the formatted output conversion routine, which could,

on big-endian platforms, potentially lead to the disclosure of sensitive

information or a denial of service (application crash). (CVE-2009-1956)

 

Note: The CVE-2009-1956 flaw only affects big-endian platforms, such as the

IBM S/390 and PowerPC. It does not affect users using the apr-util package

on little-endian platforms, due to their different organization of byte

ordering used to represent particular data.

 

A denial of service flaw was found in the apr-util Extensible Markup

Language (XML) parser. A remote attacker could create a specially-crafted

XML document that would cause excessive memory consumption when processed

by the XML decoding engine. (CVE-2009-1955)

 

A heap-based underwrite flaw was found in the way apr-util created compiled

forms of particular search patterns. An attacker could formulate a

specially-crafted search keyword, that would overwrite arbitrary heap

memory locations when processed by the pattern preparation engine.

(CVE-2009-0023)

 

All apr-util users should upgrade to these updated packages, which contain

backported patches to correct these issues. Applications using the Apache

Portable Runtime library, such as httpd, must be restarted for this update

to take effect.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.

 

This update is available via Red Hat Network. Details on how to use

the Red Hat Network to apply this update are available at

http://kbase.redhat.com/faq/docs/DOC-11259

 

5. Bugs fixed (http://bugzilla.redhat.com/):

 

503928 - CVE-2009-0023 apr-util heap buffer underwrite

504390 - CVE-2009-1956 apr-util single NULL byte buffer overflow

504555 - CVE-2009-1955 apr-util billion laughs attack
