Description

The resource system in PHP 5.0.0 through 5.2.1 allows context-dependent attackers to execute arbitrary code by interrupting the hash_update_file function via a userspace (1) error or (2) stream handler, which can then be used to destroy and modify internal resources. NOTE: it was later reported that PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 are also affected.

Affected products

• PHP: 5.0-rc1, 5.0-rc2, 5.0-rc3, 5.0.0, 5.0.1, 5.0.2 (+27)
