Description

SeaMonkey is an open source Web browser, email and newsgroup client, IRC
chat client, and HTML editor.

Several use-after-free flaws were found in SeaMonkey. Visiting a web page
containing malicious content could result in SeaMonkey executing arbitrary
code with the privileges of the user running SeaMonkey. (CVE-2010-0175,
CVE-2010-0176, CVE-2010-0177)

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-2010-0174)

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.
