CVE-2011-5094
4.3 · MEDIUMOverview
CVE-2011-5094 is a medium-severity vulnerability affecting mozilla network_security_services. It was published on June 16, 2012 and has a CVSS 2.0 base score of 4.3 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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
Remediation
Check the references section for vendor advisories and patches from mozilla. Update network_security_services to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
