CVE-2007-4657 Detail

Description

Multiple integer overflows in PHP 4 before 4.4.8, and PHP 5 before 5.2.4, allow remote attackers to obtain sensitive information (memory contents) or cause a denial of service (thread crash) via a large len value to the (1) strspn or (2) strcspn function, which triggers an out-of-bounds read. NOTE: this affects different product versions than CVE-2007-3996.

Vendor Statements (disclaimer)

Official Statement from Red Hat (09/05/2007)

The only effect of this bug is to cause the process to read from a random segment of memory, if a large "length" parameter is passed to the strspn/strcspn function, which is under the control of the script author. This bug has no security impact.
