CVE-2011-5094: n/a vulnerability

CVE-2011-5094: Mozilla Network Security Services (NSS) 3.x, with certain settings of the SSL_ENABLE_RENEGOTIATION option,...

Mozilla Network Security Services (NSS) 3.x, with certain settings of the SSL_ENABLE_RENEGOTIATION option, does not properly restrict client-initiated renegotiation within the SSL and TLS protocols, which might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection, a different vulnerability than CVE-2011-1473. NOTE: it can also be argued that it is the responsibility of server deployments, not a security library, to prevent or limit renegotiation when it is inappropriate within a specific environment

Security readout for executives and security teams

This CVE describes a denial-of-service risk in Mozilla NSS 3.x when TLS renegotiation is allowed in certain ways. An attacker may repeatedly renegotiate within one TLS connection, forcing excess CPU work. It is an availability issue, not evidence of data theft or code execution. Exposure is most plausible for internet-facing TLS services using Mozilla NSS 3.x with client-initiated renegotiation enabled or insufficiently limited. The source bundle does not identify specific downstream products, package versions, or default configurations. Prioritize exposed TLS services where availability matters, especially legacy systems. This is not marked as actively exploited and has incomplete affected-version detail, but the business impact could be service degradation if vulnerable configurations remain reachable. Mitigation focus: Check current vendor guidance for NSS and dependent products.; Disable or limit client-initiated TLS renegotiation where supported.; Review SSL_ENABLE_RENEGOTIATION settings on NSS-based services..
