CVE-2007-2500: GNU Flash Player

High severity, CVSS 10.0. EPSS: 5.4% chance of exploitation in the next 30 days.

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.

Affected products

• GNU Flash Player: up to and including 0.7.2
