Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : openssl vulnerabilities (USN-2459-1) (FREAK)

Medium Nessus Plugin ID 80471

Synopsis

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

Description

Pieter Wuille discovered that OpenSSL incorrectly handled Bignum squaring. (CVE-2014-3570)

Markus Stenberg discovered that OpenSSL incorrectly handled certain crafted DTLS messages. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2014-3571)

Karthikeyan Bhargavan discovered that OpenSSL incorrectly handled certain handshakes. A remote attacker could possibly use this issue to downgrade to ECDH, removing forward secrecy from the ciphersuite.
(CVE-2014-3572)

Antti Karjalainen, Tuomo Untinen and Konrad Kraszewski discovered that OpenSSL incorrectly handled certain certificate fingerprints. A remote attacker could possibly use this issue to trick certain applications that rely on the uniqueness of fingerprints. (CVE-2014-8275)

Karthikeyan Bhargavan discovered that OpenSSL incorrectly handled certain key exchanges. A remote attacker could possibly use this issue to downgrade the security of the session to EXPORT_RSA.
(CVE-2015-0204)

Karthikeyan Bhargavan discovered that OpenSSL incorrectly handled client authentication. A remote attacker could possibly use this issue to authenticate without the use of a private key in certain limited scenarios. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10.
(CVE-2015-0205)

Chris Mueller discovered that OpenSSL incorrect handled memory when processing DTLS records. A remote attacker could use this issue to cause OpenSSL to consume resources, resulting in a denial of service.
This issue only affected Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-0206).

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.
