Ubuntu 14.04 LTS : Mono vulnerabilities (USN-2547-1)

critical Nessus Plugin ID 82074

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2547-1 advisory.

 It was discovered that the Mono TLS implementation was vulnerable to the SKIP-TLS vulnerability. A remote attacker could possibly use this issue to perform client impersonation attacks. (CVE-2015-2318)

 It was discovered that the Mono TLS implementation was vulnerable to the FREAK vulnerability. A remote attacker or a machine-in-the-middle could possibly use this issue to force the use of insecure ciphersuites. (CVE-2015-2319)

 It was discovered that the Mono TLS implementation still supported a fallback to SSLv2. This update removes the functionality as use of SSLv2 is known to be insecure. (CVE-2015-2320)

 It was discovered that Mono incorrectly handled memory in certain circumstances. A remote attacker could possibly use this issue to cause Mono to crash, resulting in a denial of service, or to obtain sensitive information. This issue only applied to Ubuntu 12.04 LTS. (CVE-2011-0992)

 It was discovered that Mono incorrectly handled hash collisions. A remote attacker could possibly use this issue to cause Mono to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS. (CVE-2012-3543)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
