Bernd Melchers discovered that PHP’s embedded libmagic library incorrectly handled indirect offset values. An attacker could use this issue to cause PHP to consume resources or crash, resulting in a denial of service. (CVE-2014-1943)
It was discovered that PHP incorrectly handled certain values when using the imagecrop function. An attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service, obtain sensitive information, or possibly execute arbitrary code. This issue only affected Ubuntu 13.10. (CVE-2013-7226, CVE-2013-7327, CVE-2013-7328, CVE-2014-2020).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
