Ubuntu 14.04 LTS : OpenSSL regression (USN-2232-2)

medium Nessus Plugin ID 74508

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2232-2 advisory.

 USN-2232-1 fixed vulnerabilities in OpenSSL. The upstream fix for CVE-2014-0224 caused a regression for certain applications that use tls_session_secret_cb, such as wpa_supplicant. This update fixes the problem.

 Original advisory details:

 Jri Aedla discovered that OpenSSL incorrectly handled invalid DTLS

 fragments. A remote attacker could use this issue to cause OpenSSL to

 crash, resulting in a denial of service, or possibly execute arbitrary

 code. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and

 Ubuntu 14.04 LTS. (CVE-2014-0195)

 Imre Rad discovered that OpenSSL incorrectly handled DTLS recursions. A

 remote attacker could use this issue to cause OpenSSL to crash, resulting

 in a denial of service. (CVE-2014-0221)

 KIKUCHI Masashi discovered that OpenSSL incorrectly handled certain

 handshakes. A remote attacker could use this flaw to perform a

 machine-in-the-middle attack and possibly decrypt and modify traffic.

 (CVE-2014-0224)

 Felix Grbert and Ivan Fratri discovered that OpenSSL incorrectly handled

 anonymous ECDH ciphersuites. A remote attacker could use this issue to

 cause OpenSSL to crash, resulting in a denial of service. This issue only

 affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS.

 (CVE-2014-3470)

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

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

Solution

Update the affected packages.
