Red Hat Security Advisory
Synopsis: Moderate: httpd security update
Advisory ID: RHSA-2009:1108-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1108.html
Issue date: 2009-06-16
CVE Names: CVE-2009-0023 CVE-2009-1955 CVE-2009-1956
=====================================================================
1. Summary:
Updated httpd packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 3.
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 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Description:
The Apache HTTP Server is a popular Web server. The httpd package shipped
with Red Hat Enterprise Linux 3 contains an embedded copy of the Apache
Portable Runtime (APR) utility library, a free library of C data structures
and routines, which includes interfaces to support XML parsing, LDAP
connections, 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 httpd 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 httpd users should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the httpd daemon must be restarted for the 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
