Package : php5
CVE ID : CVE-2015-7803 CVE-2015-7804

Two vulnerabilities were found in PHP, a general-purpose scripting
language commonly used for web application development.

CVE-2015-7803

The phar extension could crash with a NULL pointer dereference
when processing tar archives containing links referring to
non-existing files. This could lead to a denial of service.

CVE-2015-7804

The phar extension does not correctly process directory entries
found in archive files with the name “/”, leading to a denial of
service and, potentially, information disclosure.

The update for Debian stable (jessie) contains additional bug fixes
from PHP upstream version 5.6.14, as described in the upstream
changelog:

https://php.net/ChangeLog-5.php#5.6.13

Note to users of the the oldstable distribution (wheezy): PHP 5.4 has
reached end-of-life on September 14th, 2015. As a result, there will
be no more new upstream releases. The security support of PHP 5.4 in
Debian oldstable (wheezy) will be best effort only, and you are
strongly advised to upgrade to latest Debian stable release (jessie),
which includes PHP 5.6.

For the oldstable distribution (wheezy), these problems have been fixed
in version 5.4.45-0+deb7u2.

For the stable distribution (jessie), these problems have been fixed in
version 5.6.14+dfsg-0+deb8u1.

For the testing distribution (stretch) and the unstable distribution
(sid), these problems have been fixed in version 5.6.14+dfsg-1.

We recommend that you upgrade your php5 packages.
