Description Vincent Danen 2011-11-29 18:57:08 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2011-4566 to
the following vulnerability:

Name: CVE-2011-4566
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4566
Assigned: 20111128
Reference: https://bugs.php.net/bug.php?id=60150

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.



Although the CVE description specifically indicates 5.4.0beta2 is affected, it does look like this could go back as far as PHP4.  There is an upstream patch [1] that corrects this which looks applicable even to PHP4.
