Check for the version of the mozilla package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory MDKSA-2004:021 (mozilla).
A number of vulnerabilities were discovered in Mozilla 1.4:
A malicious website could gain access to a user's authentication credentials to
a proxy server.
Script.prototype.freeze/thaw could permit a possible hacker to run arbitrary code on
A vulnerability was also discovered in the NSS security suite which ships with
Mozilla. The S/MIME implementation would permit remote attackers to cause a
Denial of Service and possibly execute arbitrary code via an S/MIME email
message containing certain unexpected ASN.1 constructs, which was demonstrated
using the NISCC test suite. NSS version 3.9 corrects these problems and has been
included in this package (which shipped with NSS 3.8).
Finally, Corsaire discovered that a number of HTTP user agents contained a flaw
in how they handle cookies. This flaw could permit a possible hacker to avoid the path
restrictions specified by a cookie's originator. According to their advisory:
'The cookie specifications detail a path argument that can be used to restrict
the areas of a host that will be exposed to a cookie. By using standard
traversal techniques this functionality can be subverted, potentially exposing
the cookie to scrutiny and use in further attacks.'
As well, a bug with Mozilla and Finnish keyboards has been corrected.
The updated packages are patched to correct these vulnerabilities.
