The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

The installed version of SeaMonkey is earlier than 2.13.1.  As such, it is potentially affected by the following security issues :

  - An unspecified error related to the WebSockets     implementation and the function     'mozilla::net::FailDelayManager::Lookup' could allow     application crashes and potentially, arbitrary code     execution. (CVE-2012-4191)

  - An unspecified error exists that could allow attackers     to bypass the 'Same Origin Policy' and access the     'Location' object. (CVE-2012-4192)

  - An error exists related to 'security wrappers' and the     function 'defaultValue()' that could allow cross-site     scripting attacks. (CVE-2012-4193)
