| Description: | Summary:
The remote host is missing an update for the 'seamonkey'
package(s) announced via the referenced advisory.
Vulnerability Insight:
SeaMonkey is an open source Web browser, email and newsgroup client, IRC
chat client, and HTML editor.
Moxie Marlinspike reported a heap overflow flaw in a regular expression
parser in the NSS library (provided by SeaMonkey) used to match common
names in certificates. A malicious website could present a
carefully-crafted certificate in such a way as to trigger the heap
overflow, leading to a crash or, possibly, arbitrary code execution with
the permissions of the user running SeaMonkey. (CVE-2009-2404)
Note: in order to exploit this issue without further user interaction, the
carefully-crafted certificate would need to be signed by a Certificate
Authority trusted by SeaMonkey, otherwise SeaMonkey presents the victim
with a warning that the certificate is untrusted. Only if the user then
accepts the certificate will the overflow take place.
All SeaMonkey users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the updated
packages, SeaMonkey must be restarted for the update to take effect.
Affected Software/OS:
seamonkey on CentOS 3
Solution:
Please install the updated packages.
CVSS Score:
