Vulnerability Insight:
Stephane Chazelas discovered that the /etc/cron.d/php5 cron job for
PHP 5.3.5 allows local users to delete arbitrary files via a symlink
attack on a directory under /var/lib/php5/. (CVE-2011-0441)
Raphael Geisert and Dan Rosenberg discovered that the PEAR installer
allows local users to overwrite arbitrary files via a symlink attack on
the package.xml file, related to the (1) download_dir, (2) cache_dir,
(3) tmp_dir, and (4) pear-build-download directories. (CVE-2011-1072,
CVE-2011-1144)
Ben Schmidt discovered that a use-after-free vulnerability in the PHP
Zend engine could allow an attacker to cause a denial of service (heap
memory corruption) or possibly execute arbitrary code. (CVE-2010-4697)
Martin Barbella discovered a buffer overflow in the PHP GD extension
that allows an attacker to cause a denial of service (application crash)
via a large number of anti- aliasing steps in an argument to the
imagepstext function. (CVE-2010-4698)
It was discovered that PHP accepts the \0 character in a pathname,
which might allow an attacker to bypass intended access restrictions
by placing a safe file extension after this character. This issue
is addressed in Ubuntu 10.04 LTS, Ubuntu 10.10, and Ubuntu 11.04.
(CVE-2006-7243)

11.04. (CVE-2011-0420)
Maksymilian Arciemowicz discovered that the _zip_name_locate
function in the PHP Zip extension does not properly handle a
ZIPARCHIVE::FL_UNCHANGED argument, which might allow an attacker to
cause a denial of service (NULL pointer dereference) via an empty
ZIP archive. This issue affected Ubuntu 8.04 LTS, Ubuntu 9.10, Ubuntu
10.04 LTS, Ubuntu 10.10, and Ubuntu 11.04. (CVE-2011-0421)
