Summary

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.

Exploit prediction

5.39% chance of exploitation in the next 30 days, higher than 92% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
