php5 - security update

Multiple vulnerabilities have been discovered in the PHP language:

• CVE-2015-2301
  Use-after-free in the phar extension.
• CVE-2015-2331
  Emmanuel Law discovered an integer overflow in the processing
  of ZIP archives, resulting in denial of service or potentially
  the execution of arbitrary code.

For the stable distribution (wheezy), these problems have been fixed in
version 5.4.39-0+deb7u1. This update also fixes a regression in the
curl support introduced in DSA 3195.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your php5 packages.
