Description

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.

Affected products

PHP: 4.0, 4.0-beta_4_patch1, 4.0-beta1, 4.0-beta2, 4.0-beta3, 4.0-beta4 (+67)
