CVE-2015-4000
With TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is
enabled on a server but not on a client, does not properly convey a
DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct
cipher-downgrade attacks by rewriting a ClientHello with DHE replaced
by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT
replaced by DHE, aka the 'Logjam' issue.
The solution in nss was to not accept bit lengths less than 1024. This
may potentially be a backwards incompatibility issue but such low bit
lengths should not be in use so it was deemed acceptable.
For Debian 7 'Wheezy', these problems have been fixed in version
2:3.14.5-1 deb7u7.
We recommend that you upgrade your nss packages.
NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.
