php5 - several

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 accept
the changes to the /etc/cron.d/php5 file. Ignoring them would leave the
system vulnerable.

For the oldstable distribution (lenny), this problem has been fixed in
version 5.2.6.dfsg.1-1+lenny10.

For the stable distribution (squeeze), this problem has been fixed in
version 5.3.3-7+squeeze1.

For the unstable distribution (sid), this problem has been fixed in
version 5.3.6-1.

Additionally, the following vulnerabilities have also been fixed in the
oldstable distribution (lenny):

• CVE-2010-3709
  Maksymilian Arciemowicz discovered that the ZipArchive class
  may dereference a NULL pointer when extracting comments from a ZIP
  archive, leading to application crash and possible denial of
  service.
• CVE-2010-3710
  Stefan Neufeind discovered that the FILTER_VALIDATE_EMAIL filter
  does not correctly handle long, to be validated, strings. Such
  crafted strings may lead to denial of service because of high memory
  consumption and application crash.
• CVE-2010-3870
  It was discovered that PHP does not correctly handle certain UTF-8
  sequences and may be used to bypass XSS protections.
• CVE-2010-4150
  Mateusz Kocielski discovered that the IMAP extension may try to
  free already freed memory when processing user credentials, leading
  to application crash and possibly arbitrary code execution.

We recommend that you upgrade your php5 packages.
