Details

The SSLv2 protocol support in the NSS library did not sufficiently

execute arbitrary code with the user's privileges. (CVE-2007-0008)

The SSLv2 protocol support in the NSS library did not sufficiently
verify the validity of client master keys presented in an SSL client
certificate. A remote attacker could exploit this to execute arbitrary
code in a server application that uses the NSS library. (CVE-2007-0009)

Various flaws have been reported that could allow an attacker to execute
arbitrary code with user privileges by tricking the user into opening a
malicious web page. (CVE-2007-0775, CVE-2007-0776,
