Input validation error in PHP - CVE-2007-1376

Vulnerability details

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The shmop functions in PHP before 4.4.5, and before 5.2.1 in the 5.x series, do not verify that their arguments correspond to a shmop resource, which allows context-dependent attackers to read and write arbitrary memory locations via arguments associated with an inappropriate resource, as demonstrated by a GD Image resource.
