Ubuntu Security Notice (C) 2014 Canonical, Inc. / NASL script (C) 2014 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.

Jüri 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 Gröbert and Ivan FratriÄ 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).

Solution :

Update the affected libssl0.9.8 and / or libssl1.0.0 packages.
