Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, does not properly restrict public values in Diffie-Hellman key exchanges, which makes it easier for remote attackers to bypass cryptographic protection mechanisms in ticket handling by leveraging use of a certain value.

Security readout for executives and security teams

This old Mozilla NSS flaw affects how some products handled Diffie-Hellman key exchange values. In affected versions, a remote attacker could make it easier to bypass cryptographic protections related to ticket handling. The bundle does not show active exploitation or a CVSS score. Exposure is most likely on legacy systems running old Mozilla applications, old libnss packages, or downstream appliances/products that embedded NSS and were not patched through vendor updates. Treat this as a legacy cryptography exposure. It is not presented as actively exploited, but unpatched NSS in browsers, mail clients, or embedded products should be removed from sensitive environments. Mitigation focus: Upgrade NSS to 3.15.4 or later where applicable.; Update Firefox, Firefox ESR, Thunderbird, and SeaMonkey beyond listed fixed versions.; Apply relevant OS vendor security updates for NSS packages..
