server/parser/sprite_definition.cpp in GNU Gnash (aka GNU Flash Player) 0.7.2 allows remote attackers to execute arbitrary code via a large number of SHOWFRAME elements within a DEFINESPRITE element, which triggers memory corruption and enables the attacker to call free with an arbitrary address, probably resultant from a buffer overflow.
