Description Tomas Hoger 2010-07-27 10:08:31 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2010-1861 to
the following vulnerability:

The sysvshm extension for PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent attackers to write to arbitrary memory addresses by using an object's __sleep function to interrupt an internal call to the shm_put_var function, which triggers access of a freed resource.

Red Hat does not consider interruption issues allowing safe_mode / open_basedir
restriction bypass to be security sensitive.  For more details see
