Mandriva Linux Security Advisory 2011-197

Posted Dec 30, 2011

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2011-197 - Integer overflow in the exif_process_IFD_TAG function in exif.c in the exif extension in PHP 5.4.0beta2 on 32-bit platforms allows remote attackers to read the contents of arbitrary memory locations or cause a denial of service via a crafted offset_val value in an EXIF header in a JPEG file, a different vulnerability than CVE-2011-0708. PHP before 5.3.9 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service by sending many crafted parameters. The updated packages have been patched to correct this issue.
