The Mozilla Network Security Service is a library implementing security features like SSL v2/v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME and X.509 certificates.
iDefense has reported two potential buffer overflow vulnerabilities found by researcher “regenrecht” in the code implementing the SSLv2 protocol.
A remote attacker could send a specially crafted SSL master key to a server using NSS for the SSLv2 protocol, or entice a user to connect to a malicious server with a client-side application using NSS like one of the Mozilla products. This could trigger the vulnerabilities and result in the possible execution of arbitrary code with the rights of the vulnerable application.
Disable the SSLv2 protocol in the applications using NSS.
All NSS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/nss-3.11.5"
