The remote Debian host is missing a security-related 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.
Upgrade the php5 packages. 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.
