CVE-2014-9426: PHP

High severity, CVSS 7.3. EPSS: 2.1% chance of exploitation in the next 30 days.

The apprentice_load function in libmagic/apprentice.c in the Fileinfo component in PHP through 5.6.4 attempts to perform a free operation on a stack-based character array, which allows remote attackers to cause a denial of service (memory corruption or application crash) or possibly have unspecified other impact via unknown vectors. NOTE: this is disputed by the vendor because the standard erealloc behavior makes the free operation unreachable

Affected products

• PHP PHP: up to and including 5.6.4
