GLSA-200907-03 : APR Utility Library: Multiple vulnerabilities

High Nessus Plugin ID 39614

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200907-03 (APR Utility Library: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in the APR Utility Library:
Matthew Palmer reported a heap-based buffer underflow while compiling search patterns in the apr_strmatch_precompile() function in strmatch/apr_strmatch.c (CVE-2009-0023).
kcope reported that the expat XML parser in xml/apr_xml.c does not limit the amount of XML entities expanded recursively (CVE-2009-1955).
C. Michael Pilato reported an off-by-one error in the apr_brigade_vprintf() function in buckets/apr_brigade.c (CVE-2009-1956).
Impact :

A remote attacker could exploit these vulnerabilities to cause a Denial of Service (crash or memory exhaustion) via an Apache HTTP server running mod_dav or mod_dav_svn, or using several configuration files.
Additionally, a remote attacker could disclose sensitive information or cause a Denial of Service by sending a specially crafted input. NOTE:
Only big-endian architectures such as PPC and HPPA are affected by the latter flaw.
Workaround :

There is no known workaround at this time.

Solution

All Apache Portable Runtime Utility Library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/apr-util-1.3.7'
