The remote Debian host is missing a security-related update.
Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2014-3538 It was discovered that the original fix for CVE-2013-7345 did not sufficiently address the problem. A remote attacker could still cause a denial of service (CPU consumption) via a specially crafted input file that triggers backtracking during processing of an awk regular expression rule. - CVE-2014-3587 It was discovered that the CDF parser of the fileinfo module does not properly process malformed files in the Composite Document File (CDF) format, leading to crashes. - CVE-2014-3597 It was discovered that the original fix for CVE-2014-4049 did not completely address the issue. A malicious server or man-in-the-middle attacker could cause a denial of service (crash) and possibly execute arbitrary code via a crafted DNS TXT record. - CVE-2014-4670 It was discovered that PHP incorrectly handled certain SPL Iterators. A local attacker could use this flaw to cause PHP to crash, resulting in a denial of service.
Upgrade the php5 packages. For the stable distribution (wheezy), these problems have been fixed in version 5.4.4-14+deb7u13. In addition, this update contains several bugfixes originally targeted for the upcoming Wheezy point release.
