CVE-2011-0421

Status Candidate

Overview

The _zip_name_locate function in zip_name_locate.c in the Zip extension in PHP before 5.3.6 does not properly handle a ZIPARCHIVE::FL_UNCHANGED argument, which might allow context-dependent attackers to cause a denial of service (NULL pointer dereference) via an empty ZIP archive that is processed with a (1) locateName or (2) statName operation.

Ubuntu Security Notice 1126-1 - 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/. 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. 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. 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. Various other issues with PHP 5 were also identified and resolved.
