Debian Security Advisory
DSA-3380-1 php5 -- security update
- Date Reported:
- 27 Oct 2015
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2015-7803, CVE-2015-7804.
- More information:
Two vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development.
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.
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:
Note to users of 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.
