Stephane Chazelas discovered that the cronjob of the PHP 5 package in Debian suffers from a race condition which might be used to remove arbitrary files from a system (CVE-2011-0441 ).

When upgrading your php5-common package take special care to acceptthe changes to the /etc/cron.d/php5 file. Ignoring them would leave the system vulnerable.

The following DoS condition in IMAP extension was fixed in PHP 5.3.4 and PHP 5.2.15 :

A remote user can send specially crafted IMAP user name or password data to trigger a double free memory error in 'ext/imap/php_imap.c' and cause the target service to crash.

It may be possible to execute arbitrary code. However, code execution was not confirmed.

Security Enhancements and Fixes in PHP 5.3.4 :

  - Fixed crash in zip extract method (possible CWE-170).

    - Paths with NULL in them (foo\0bar.txt) are now       considered as invalid (CVE-2006-7243).

    - Fixed a possible double free in imap extension       (Identified by Mateusz Kocielski). (CVE-2010-4150).

    - Fixed NULL pointer dereference in       ZipArchive::getArchiveComment. (CVE-2010-3709).

    - Fixed possible flaw in open_basedir (CVE-2010-3436).

    - Fixed MOPS-2010-24, fix string validation.
      (CVE-2010-2950).

    - Fixed symbolic resolution support when the target is a       DFS share.

    - Fixed bug #52929 (Segfault in filter_var with       FILTER_VALIDATE_EMAIL with large amount of data)       (CVE-2010-3710).

Key Bug Fixes in PHP 5.3.4 include :

  - Added stat support for zip stream.

    - Added follow_location (enabled by default) option for       the http stream support.

    - Added a 3rd parameter to get_html_translation_table.
      It now takes a charset hint, like htmlentities et al.

    - Implemented FR #52348, added new constant       ZEND_MULTIBYTE to detect zend multibyte at runtime.
