A memory corruption flaw was found in the way SeaMonkey decoded
certain PNG images. An attacker could create a specially crafted PNG
image that, when opened, could cause SeaMonkey to crash or,
potentially, execute arbitrary code with the privileges of the user
running SeaMonkey. (CVE-2010-1205)
A same-origin policy bypass flaw was found in SeaMonkey. An attacker
could create a malicious web page that, when viewed by a victim, could

All SeaMonkey users should upgrade to these updated packages, which
correct these issues. After installing the update, SeaMonkey must be
