Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

A number of vulnerabilities have been found and corrected in PHP :

improve mbfl_filt_conv_html_dec_flush() error handling in
ext/mbstring/libmbfl/filters/mbfilter_htmlent.c (CVE-2008-5557).
Additionally on Mandriva Linux 2009.0 and up the php-mbstring module
is linked against a separate shared libmbfl library that also have
been patched to address CVE-2008-5557.

Directory traversal vulnerability in the ZipArchive::extractTo
function in PHP 5.2.6 and earlier allows context-dependent attackers
to write arbitrary files via a ZIP file with a file whose name
contains .. (dot dot) sequences. (CVE-2008-5658)

make sure the page_uid and page_gid get initialized properly in
ext/standard/basic_functions.c. Also, init server_context before
processing config variables in sapi/apache/mod_php5.c (CVE-2008-5624).

enforce restrictions when merging in dir entry in
sapi/apache/mod_php5.c and sapi/apache2handler/apache_config.c
(CVE-2008-5625).

On 2008.1, 2009.0 and cooker (2009.1) seen on x86_64 and with the
latest phpmyadmin 3.1.2 software made apache+php segfault (#26274,
#45864). This problem has been addressed by using -O0 for compiler
optimization and by using -fno-strict-aliasing. Either the bug is in
php and/or in gcc 4.3.2. Preferable just make it work as expected for
now.

In addition, the updated packages provide a number of bug fixes.

The updated packages have been patched to correct these issues.

Solution :

Update the affected packages.
