CVE-2009-0023

Status Candidate

Overview

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, which triggers a heap-based buffer underflow.

Ubuntu Security Notice 786-1

Ubuntu Security Notice USN-786-1 - Matthew Palmer discovered an underflow flaw in apr-util. An attacker could cause a denial of service via application crash in Apache using a crafted SVNMasterURI directive, .htaccess file, or when using mod_apreq2. Applications using libapreq2 are also affected. It was discovered that the XML parser did not properly handle entity expansion. A remote attacker could cause a denial of service via memory resource consumption by sending a crafted request to an Apache server configured to use mod_dav or mod_dav_svn. C. Michael Pilato discovered an off-by-one buffer overflow in apr-util when formatting certain strings. For big-endian machines (powerpc, hppa and sparc in Ubuntu), a remote attacker could cause a denial of service or information disclosure leak. All other architectures for Ubuntu are not considered to be at risk.
