Mozilla Network Security Services (NSS) Client Master Key buffer overflow

nss-clientmasterkey-bo (32663) The risk level is classified as HighHigh Risk

Description:

Multiple products using the Mozilla Network Security Services (NSS) library are vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the SSLv2 service. By sending a specially-crafted SSLv2 certificate with a small Client Master Key, a remote attacker could overflow a buffer and execute arbitrary code on the system.
