Ubuntu 12.04 LTS / 13.10 / 14.04 LTS : openssl regression (USN-2232-2)

High Nessus Plugin ID 74508

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

Juri 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 man-in-the-middle attack and possibly decrypt and modify traffic. (CVE-2014-0224)

Felix Grobert and Ivan Fratric 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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libssl1.0.0 package.
