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

related to the call time pass by reference feature.

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