USN-786-1: apr-util vulnerabilities
Posted on: 06/10/2009 11:20 PM

A new apr-util vulnerabilities update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-786-1 June 10, 2009
apr-util vulnerabilities
CVE-2009-0023, CVE-2009-1955, CVE-2009-1956
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 8.10
Ubuntu 9.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.04 LTS:
libaprutil1 1.2.12+dfsg-3ubuntu0.1

Ubuntu 8.10:
libaprutil1 1.2.12+dfsg-7ubuntu0.1

Ubuntu 9.04:
libaprutil1 1.2.12+dfsg-8ubuntu0.1

After a standard system upgrade you need to restart any services that use
apr-util, such as Apache or svnserve, to effect the necessary changes.

Details follow:

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. (CVE-2009-0023)

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. (CVE-2009-1955)

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. (CVE-2009-1956)
