Description

The donote function in readelf.c in file through 5.20, as used in the Fileinfo component in PHP 5.4.34, does not ensure that sufficient note headers are present, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted ELF file.

How to fix

Upgrade to a fixed version: PHP 5.4.35, 5.5.19, 5.6.3. Check the vendor advisory for mitigations.
