Debian DLA-176-1 : mono security update

critical Nessus Plugin ID 82161

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Three issues with Mono's TLS stack are addressed.

CVE-2015-2318

Mono's implementation of the SSL/TLS stack failed to check the order of the handshake messages. Which would allow various attacks on the protocol to succeed. ('SKIP-TLS')

CVE-2015-2319

Mono's implementation of SSL/TLS also contained support for the weak EXPORT cyphers and was susceptible to the FREAK attack.

CVE-2015-2320

Mono contained SSLv2 fallback code, which is no longer needed and can be considered insecure.

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.

Solution

Upgrade the affected packages.
