Ubuntu 9.10 : nss regression (USN-927-2)

Ubuntu Security Notice (C) 2010-2015 Canonical, Inc. / NASL script (C) 2010-2015 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

USN-927-1 fixed vulnerabilities in NSS. Upstream NSS 3.12.6 added an
additional checksum verification on libnssdbm3.so, but the Ubuntu
packaging did not create this checksum. As a result, Firefox could not
initialize the security component when the NSS Internal FIPS PKCS #11
Module was enabled. This update fixes the problem.

We apologize for the inconvenience.

Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3
protocols. If an attacker could perform a man in the middle attack at
the start of a TLS connection, the attacker could inject arbitrary
content at the beginning of the user's session. This update adds
support for the new new renegotiation extension and will use it when
the server supports it.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.0
CVSS Temporal Score : 4.3
Public Exploit Available : true
