Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2010-1211, CVE-2010-2753, CVE-2010-1214)
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 steal private data from a different website the victim has loaded with SeaMonkey. (CVE-2010-2754)
A flaw was found in the way SeaMonkey displayed the location bar when visiting a secure web page. A malicious server could use this flaw to present data that appears to originate from a secure server, even though it does not. (CVE-2010-2751)
All SeaMonkey users should upgrade to these updated packages, which correct these issues. After installing the update, SeaMonkey must be restarted for the changes to take effect.
