The (1) iconv_mime_decode, (2) iconv_substr, and (3) iconv_mime_encode
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

Comment 8 Tomas Hoger 2010-07-26 09:37:19 UTC 
Statement:

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