Debian DSA-2195-1 : php5 - several vulnerabilities

medium Nessus Plugin ID 52719

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the php5 packages.

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.

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.
