the following vulnerability:

The (1) trim, (2) ltrim, (3) rtrim, and (4) substr_replace functions
in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allow
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 6 Tomas Hoger 2010-07-26 09:13:40 UTC 
Statement:

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