Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS : openssl vulnerabilities (USN-2308-1)

High Nessus Plugin ID 77085

Synopsis

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

Description

Adam Langley and Wan-Teh Chang discovered that OpenSSL incorrectly handled certain DTLS packets. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service.
(CVE-2014-3505)

Adam Langley discovered that OpenSSL incorrectly handled memory when processing DTLS handshake messages. A remote attacker could use this issue to cause OpenSSL to consume memory, resulting in a denial of service. (CVE-2014-3506)

Adam Langley discovered that OpenSSL incorrectly handled memory when processing DTLS fragments. A remote attacker could use this issue to cause OpenSSL to leak memory, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS.
(CVE-2014-3507)

Ivan Fratric discovered that OpenSSL incorrectly leaked information in the pretty printing functions. When OpenSSL is used with certain applications, an attacker may use this issue to possibly gain access to sensitive information. (CVE-2014-3508)

Gabor Tyukasz discovered that OpenSSL contained a race condition when processing serverhello messages. A malicious server could use this issue to cause clients to crash, resulting in a denial of service.
This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS.
(CVE-2014-3509)

Felix Grobert discovered that OpenSSL incorrectly handled certain DTLS handshake messages. A malicious server could use this issue to cause clients to crash, resulting in a denial of service.
(CVE-2014-3510)

David Benjamin and Adam Langley discovered that OpenSSL incorrectly handled fragmented ClientHello messages. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be used to force a protocol downgrade to TLS 1.0. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3511)

Sean Devlin and Watson Ladd discovered that OpenSSL incorrectly handled certain SRP parameters. A remote attacker could use this with applications that use SRP to cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3512)

Joonas Kuorilehto and Riku Hietamaki discovered that OpenSSL incorrectly handled certain Server Hello messages that specify an SRP ciphersuite. A malicious server could use this issue to cause clients to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-5139).

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.
