SuSE 11.2 / 11.3 Security Update : Mozilla NSS (SAT Patch Numbers 8484 / 8485)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

Mozilla NSS has been updated to 3.15.2 (bnc#847708) bringing various
features and bugfixes :

The main feature is TLS 1.2 support and its dependent algorithms.

- Support for AES-GCM ciphersuites that use the SHA-256
PRF

- MD2, MD4, and MD5 signatures are no longer accepted for
OCSP or CRLs

- Add PK11_CipherFinal macro

- sizeof() used incorrectly

- nssutil_ReadSecmodDB() leaks memory

- Allow SSL_HandshakeNegotiatedExtension to be called
before the handshake is finished.

- Deprecate the SSL cipher policy code

- Avoid uninitialized data read in the event of a
decryption failure. (CVE-2013-1739) Changes coming with
version 3.15.1 :

- TLS 1.2 (RFC 5246) is supported. HMAC-SHA256 cipher
suites (RFC 5246 and RFC 5289) are supported, allowing
TLS to be used without MD5 and SHA-1. Note the following
limitations: The hash function used in the signature for
TLS 1.2 client authentication must be the hash function
of the TLS 1.2 PRF, which is always SHA-256 in NSS
3.15.1. AES GCM cipher suites are not yet supported.

- some bugfixes and improvements Changes with version 3.15

- New Functionality

- Support for OCSP Stapling (RFC 6066, Certificate Status
Request) has been added for both client and server
sockets. TLS client applications may enable this via a
call to SSL_OptionSetDefault(SSL_ENABLE_OCSP_STAPLING,
PR_TRUE);

- Added function SECITEM_ReallocItemV2. It replaces
function SECITEM_ReallocItem, which is now declared as
obsolete.

- Support for single-operation (eg: not multi-part)
symmetric key encryption and decryption, via
PK11_Encrypt and PK11_Decrypt.

- certutil has been updated to support creating name
constraints extensions.
