Red Hat Security Advisory 2014-1766-01
Posted Oct 30, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-1766-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. A buffer overflow flaw was found in the Exif extension. A specially crafted JPEG or TIFF file could cause a PHP application using the exif_thumbnail() function to crash or, possibly, execute arbitrary code. Multiple buffer overflow flaws were found in the way PHP parsed DNS responses. A malicious DNS server or a man-in-the-middle attacker could use these flaws to crash or, possibly, execute arbitrary code with the privileges of a PHP application that uses the dns_get_record() function.

Red Hat Security Advisory 2014-1013-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. PHP's fileinfo module provides functions used to identify a particular file according to the type of data contained by the file. A denial of service flaw was found in the File Information extension rules for detecting AWK files. A remote attacker could use this flaw to cause a PHP application using fileinfo to consume an excessive amount of CPU. Multiple denial of service flaws were found in the way the File Information extension parsed certain Composite Document Format files. A remote attacker could use either of these flaws to crash a PHP application using fileinfo via a specially crafted CDF file.

Mandriva Linux Security Advisory 2014-130

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2014-130 - The unserialize() function in PHP before 5.4.30 and 5.5.14 has a Type Confusion issue related to the SPL ArrayObject and SPLObjectStorage Types. It was discovered that PHP is vulnerable to a heap-based buffer overflow in the DNS TXT record parsing. A malicious server or man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application uses dns_get_record() to perform a DNS query. A flaw was found in the way file parsed property information from Composite Document Files (CDF) files, where the mconvert() function did not correctly compute the truncated pascal string size. Multiple flaws were found in the way file parsed property information from Composite Document Files files, due to insufficient boundary checks on buffers. PHP contains a bundled copy of the file utility's libmagic library, so it was vulnerable to this issue. It has been updated to versions 5.5.14, which fix this issue and several other bugs. The phpinfo() function in PHP before 5.4.30 and 5.5.14 has a Type Confusion issue that can cause it to leak arbitrary process memory. Additionally, php-apc has been rebuilt against the updated php packages and the php-timezonedb packages has been upgraded to the 2014.5 version.

Ubuntu Security Notice USN-2254-2
Posted Jun 25, 2014
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2254-2 - USN-2254-1 fixed vulnerabilities in PHP. The fix for CVE-2014-0185 further restricted the permissions on the PHP FastCGI Process Manager (FPM) UNIX socket. This update grants socket access to the www-data user and group so installations and documentation relying on the previous socket permissions will continue to function. Christian Hoffmann discovered that the PHP FastCGI Process Manager (FPM) set incorrect permissions on the UNIX socket. A local attacker could use this issue to possibly elevate their privileges. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS. Francisco Alonso discovered that the PHP Fileinfo component incorrectly handled certain CDF documents. A remote attacker could use this issue to cause PHP to hang or crash, resulting in a denial of service. Stefan Esser discovered that PHP incorrectly handled DNS TXT records. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
