Integer overflow in the regcomp implementation in the Henry Spencer BSD regex library (aka rxspencer) alpha3.8.g5 on 32-bit platforms, as used in NetBSD through 6.1.5 and other products, might allow context-dependent attackers to execute arbitrary code via a large regular expression that leads to a heap-based buffer overflow.

Affected: Ubuntu:14.04:LTS: php5

It was discovered that PHP incorrectly handled cleanup when used with Apache 2.4. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-3330)

It was discovered that PHP incorrectly handled opening tar, zip or phar archives through the PHAR extension. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-3329)

It was discovered that PHP incorrectly handled regular expressions. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-2305)

Paulos Yibelo discovered that PHP incorrectly handled moving files when a pathname contained a null character. A remote attacker could use this issue to possibly bypass filename restrictions. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-2348)

It was discovered that PHP incorrectly handled unserializing PHAR files. A remote attacker could use this issue to cause PHP to possibly expose sensitive information. (CVE-2015-2783)

Taoguang Chen discovered that PHP incorrectly handled unserializing certain objects. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-2787)
