Secunia Advisory SA14792

Where:

From remote

Impact:

Unknown, DoS, System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Multiple vulnerabilities have been reported in PHP, where some have an unknown impact and others can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.

1) Errors within the "php_handle_iff()" and "php_handle_jpeg()" functions called by the "getimagesize()" PHP function can be exploited to cause infinite loops and consume all available CPU resources via a specially crafted image.

This has been reported in versions 4.2.2, 4.3.9, 4.3.10, and 5.0.3. Other versions may also be affected.

2) An integer overflow in the "exif_process_IFD_TAG()" function in "exif.c" in the exif extension may be exploited to execute arbitrary code via an application processing EXIF tags of uploaded images.

3) An error in the processing of exif data in "exif.c" may be exploited to cause an infinite stack recursion via an application processing EXIF headers of uploaded images.

4) Multiple unspecified security issues exist in the fbsql extensions and in the "unserialize()" and "swf_definepoly()" PHP functions.

Other bugs have also been reported where some may be security related.


Solution:
Update to version 4.3.11 or 5.0.4.
