The remote host is missing updates announced in
advisory RHSA-2007:0077.
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 malformed
JavaScript code. A malicious web page could execute JavaScript code in such
a way that may result in SeaMonkey crashing or executing arbitrary code as
the user running SeaMonkey. (CVE-2007-0775, CVE-2007-0777)
Several cross-site scripting (XSS) flaws were found in the way SeaMonkey
processed certain malformed web pages. A malicious web page could display
misleading information which may result in a user unknowingly divulging
sensitive information such as a password. (CVE-2006-6077, CVE-2007-0995,
CVE-2007-0996)
A flaw was found in the way SeaMonkey cached web pages on the local disk. A
malicious web page may be able to inject arbitrary HTML into a browsing
session if the user reloads a targeted site. (CVE-2007-0778)
A flaw was found in the way SeaMonkey displayed certain web content. A
malicious web page could generate content which could overlay user
interface elements such as the hostname and security indicators, tricking a
user into thinking they are visiting a different site. (CVE-2007-0779)
Two flaws were found in the way SeaMonkey displayed blocked popup windows.
If a user can be convinced to open a blocked popup, it is possible to read
arbitrary local files, or conduct an XSS attack against the user.
(CVE-2007-0780, CVE-2007-0800)
Two buffer overflow flaws were found in the Network Security Services (NSS)
code for processing the SSLv2 protocol. Connecting to a malicious secure
web server could cause the execution of arbitrary code as the user running
SeaMonkey. (CVE-2007-0008, CVE-2007-0009)
A flaw was found in the way SeaMonkey handled the location.hostname value
during certain browser domain checks. This flaw could allow a malicious web
site to set domain cookies for an arbitrary site, or possibly perform an
XSS attack. (CVE-2007-0981)
Users of SeaMonkey are advised to upgrade to these erratum packages, which
contain SeaMonkey version 1.0.8 that corrects these issues.
