Ubuntu 10.04 LTS / 12.04 LTS / 13.10 / 14.04 LTS : openssl regression (USN-2232-3)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

USN-2232-1 fixed vulnerabilities in OpenSSL. The upstream fix for
CVE-2014-0224 caused a regression for certain applications that use
renegotiation, such as PostgreSQL. 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 libssl0.9.8 and / or libssl1.0.0 packages.

Risk factor :

High / CVSS Base Score : 9.3
