A denial of service flaw was found in the way the File Information (fileinfo) extension parsed certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file.(CVE-2014-3479)

An ouf-of-bounds read flaw was found in the way the file utility processed certain Pascal strings. A remote attacker could cause an application using the file utility (for example, PHP using the fileinfo module) to crash if it was used to identify the type of the attacker-supplied file.(CVE-2014-9652)

A denial of service flaw was found in the way the File Information (fileinfo) extension parsed certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file.(CVE-2014-0207)

A denial of service flaw was found in the way the File Information (fileinfo) extension parsed certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file.(CVE-2014-3480)

It was found that the fix for CVE-2012-1571 was incomplete, the File Information (fileinfo) extension did not correctly parse certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file.(CVE-2014-3587)

A buffer overflow flaw was found in the way the File Information (fileinfo) extension processed certain Pascal strings. A remote attacker able to make a PHP application using fileinfo convert a specially crafted Pascal string provided by an image file could cause that application to crash.(CVE-2014-3478)

Multiple flaws were found in the File Information (fileinfo) extension regular expression rules for detecting various files. A remote attacker could use either of these flaws to cause a PHP application using fileinfo to consume an excessive amount of CPU.(CVE-2014-3538)

A denial of service flaw was found in the way the File Information (fileinfo) extension parsed certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file.(CVE-2014-3487)
