CVSS v2.0
4.3
Medium
| Vector | AV:N/AC:M/Au:N/C:N/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
PHP versions prior to 5.3.6
Description
The issue is caused by an incorrect cast in the Exif extension, leading to a buffer over-read when processing a crafted Image File Directory (IFD) in an image. This allows remote attackers to cause a denial of service, resulting in an application crash. The vulnerability exists due to incorrect calculations in the exif.c file of the Exif extension in PHP.
Recommendations
For versions prior to 5.3.6, update to version 5.3.6 or later to resolve the issue. As a temporary workaround, consider restricting the use of the Exif extension until a patch is applied. Avoid using the Exif extension to process untrusted images until the issue is resolved.
