Description Tomas Hoger 2010-07-26 19:02:58 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2010-1862 to the following vulnerability:

The chunk_split function in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent attackers to obtain sensitive information (memory contents) by causing a userspace interruption of an internal function, related to the call time pass by reference feature.

Comment 3 Tomas Hoger 2010-07-26 19:04:48 UTC 
Statement:

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