Mandriva Linux Security Advisory 2009:314: apr

Article Source Mandriva Linux Security Advisories

Multiple security vulnerabilities has been identified and fixed in
apr and apr-util:

Multiple integer overflows in the Apache Portable Runtime (APR)
library and the Apache Portable Utility library (aka APR-util)
0.9.x and 1.3.x allow remote attackers to cause a denial of service
(application crash) or possibly execute arbitrary code via vectors that
trigger crafted calls to the (1) allocator_alloc or (2) apr_palloc
function in memory/unix/apr_pools.c in APR; or crafted calls to
the (3) apr_rmm_malloc, (4) apr_rmm_calloc, or (5) apr_rmm_realloc
function in misc/apr_rmm.c in APR-util; leading to buffer overflows.
NOTE: some of these details are obtained from third party information
(CVE-2009-2412).

The apr_strmatch_precompile function in strmatch/apr_strmatch.c in
Apache APR-util before 1.3.5 allows remote attackers to cause a denial
of service (daemon crash) via crafted input involving (1) a .htaccess
file used with the Apache HTTP Server, (2) the SVNMasterURI directive
in the mod_dav_svn module in the Apache HTTP Server, (3) the mod_apreq2
module for the Apache HTTP Server, or (4) an application that uses
the libapreq2 library, related to an underflow flaw. (CVE-2009-0023).

The expat XML parser in the apr_xml_* interface in xml/apr_xml.c in
Apache APR-util before 1.3.7, as used in the mod_dav and mod_dav_svn
modules in the Apache HTTP Server, allows remote attackers to
cause a denial of service (memory consumption) via a crafted XML
document containing a large number of nested entity references, as
demonstrated by a PROPFIND request, a similar issue to CVE-2003-1564
(CVE-2009-1955).

Off-by-one error in the apr_brigade_vprintf function in Apache APR-util
before 1.3.5 on big-endian platforms allows remote attackers to obtain
sensitive information or cause a denial of service (application crash)
via crafted input (CVE-2009-1956).

Packages for 2008.0 are being provided due to extended support for
Corporate products.

The updated packages have been patched to prevent this.
