Mandriva Linux Security Advisory : apr (MDVSA-2009:314)

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

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 provided for Corporate Desktop 2008.0
customers

The updated packages have been patched to prevent this.

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 8.7
(CVSS2#E:ND/RL:OF/RC:C)
