(RHSA-2006:0608) seamonkey security update

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

Several flaws were found in the way SeaMonkey processed certain javascript
actions. A malicious web page could execute arbitrary javascript
instructions with the permissions of “chrome”, allowing the page to steal
sensitive information or install browser malware. (CVE-2006-3807,
CVE-2006-3809, CVE-2006-3812)

Several denial of service flaws were found in the way SeaMonkey processed
certain web content. A malicious web page could crash the browser or
possibly execute arbitrary code as the user running SeaMonkey.
(CVE-2006-3801, CVE-2006-3677, CVE-2006-3113, CVE-2006-3803, CVE-2006-3805,
CVE-2006-3806, CVE-2006-3811)

A buffer overflow flaw was found in the way SeaMonkey Messenger displayed
malformed inline vcard attachments. If a victim viewed an email message
containing a carefully crafted vcard, it was possible to execute arbitrary
code as the user running SeaMonkey Messenger. (CVE-2006-3804)

Several flaws were found in the way SeaMonkey processed certain javascript
actions. A malicious web page could conduct a cross-site scripting attack
or steal sensitive information (such as cookies owned by other domains).
(CVE-2006-3802, CVE-2006-3810)

A flaw was found in the way SeaMonkey processed Proxy AutoConfig scripts. A
malicious Proxy AutoConfig server could execute arbitrary javascript
instructions with the permissions of “chrome”, allowing the page to steal
sensitive information or install browser malware. (CVE-2006-3808)

Users of SeaMonkey are advised to upgrade to this update, which contains
SeaMonkey version 1.0.3 that corrects these issues.
