Mandriva Linux Security Advisory : apr (MDVSA-2009:314)
critical Nessus Plugin ID 43000
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.
