Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.04 - Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in OpenSSL.

Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

Praveen Kariyanahalli, Ivan Fratric and Felix Groebert discovered that OpenSSL incorrectly handled memory when buffering DTLS data. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-8176)

Joseph Barr-Pixton discovered that OpenSSL incorrectly handled malformed ECParameters structures. A remote attacker could use this issue to cause OpenSSL to hang, resulting in a denial of service. (CVE-2015-1788)

Robert Swiecki and Hanno Böck discovered that OpenSSL incorrectly handled certain ASN1_TIME strings. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2015-1789)

Michal Zalewski discovered that OpenSSL incorrectly handled missing content when parsing ASN.1-encoded PKCS#7 blobs. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2015-1790)

Emilia Käsper discovered that OpenSSL incorrectly handled NewSessionTicket when being used by a multi-threaded client. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2015-1791)

Johannes Bauer discovered that OpenSSL incorrectly handled verifying signedData messages using the CMS code. A remote attacker could use this issue to cause OpenSSL to hang, resulting in a denial of service. (CVE-2015-1792)

As a security improvement, this update also modifies OpenSSL behaviour to reject DH key sizes below 768 bits, preventing a possible downgrade attack.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.04:
libssl1.0.0 1.0.1f-1ubuntu11.4

Ubuntu 14.10:
libssl1.0.0 1.0.1f-1ubuntu9.8

Ubuntu 14.04 LTS:
libssl1.0.0 1.0.1f-1ubuntu2.15

Ubuntu 12.04 LTS:
libssl1.0.0 1.0.1-4ubuntu5.31

After a standard system update you need to reboot your computer to make all the necessary changes.

Title: AIX OpenSSL NewSessionTicket vulnerability
Description: Race condition in the ssl3_get_new_session_ticket function in ssl/s3_clnt.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b, when used for a multi-threaded client, allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact by providing a NewSessionTicket during an attempt to reuse a ticket that had been obtained earlier.
