Heap-based buffer overflow in
ext/mbstring/libmbfl/filters/mbfilter_htmlent.c in the mbstring extension
in PHP 4.3.0 through 5.2.6 allows context-dependent attackers to execute
arbitrary code via a crafted string containing an HTML entity, which is not
properly handled during Unicode conversion, related to the (1)
mb_convert_encoding, (2) mb_check_encoding, (3) mb_convert_variables, and
(4) mb_parse_str functions.
