The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  • Mozilla: Malicious Extension could obtain auth codes from OAuth login flows (CVE-2020-6823)

  • Mozilla Firefox through 27 sends HTTP Cookie headers without first validating that they have the required character-set restrictions, which allows remote attackers to conduct the equivalent of a persistent Logout CSRF attack via a crafted parameter that forces a web application to set a malformed cookie within an HTTP response. (CVE-2013-6167)

  • Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain sensitive information by sniffing the network during a session in which there was an incorrect decision to accept a compromised and revoked certificate. (CVE-2014-8642)

Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
