A vulnerability has been found in gnash:

CVE-2007-2500:
"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."

At least 0.7.2-1 in lenny is affected. Please check whether this is fixed
in 0.7.2+cvs20070428.1515-1.
