Several vulnerabilities have been identified in Gnash, the GNU Flash
player.
CVE-2012-1175
Tielei Wang from Georgia Tech Information Security Center discovered a
vulnerability in GNU Gnash which is caused due to an integer overflow
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
Alexander Kurtz discovered an unsafe management of HTTP cookies. Cookie
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.
CVE-2010-4337
Jakub Wilk discovered an unsafe management of temporary files during the
build process. 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.
