Several vulnerabilities have been identified in Gnash, the GNU Flash
player.

CVE-2012-1175

Tielei Wang from Georgia Tech Information Security Center discovered a

error and can be exploited to cause a heap-based buffer overflow by
tricking a user into opening a specially crafted SWF file.

CVE-2011-4328

files are stored under /tmp and have predictable names, vulnerability
that allows a local attacker to overwrite arbitrary files the users has
write permissions for, and are also world-readable which may cause
information leak.

version 0.8.8-5+squeeze1.
