CVE-2018-0734

TITLE

OpenSSL Encryption problem vulnerability

DESCRIPTION

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p). OpenSSL is prone to a local information-disclosure vulnerability. Local attackers can exploit this issue to obtain sensitive information. This may aid in further attacks. The product supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, secure hash algorithms, etc. The vulnerability stems from incorrect use of relevant cryptographic algorithms by network systems or products, resulting in improperly encrypted content, weak encryption, and storing sensitive information in plain text.

(CVE-2018-0734) Samuel Weiser discovered that OpenSSL incorrectly handled ECDSA signing. This issue only affected Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2018-0735) Billy Bob Brumley, Cesar Pereida Garcia, Sohaib ul Hassan, Nicola Tuveri, and Alejandro Cabrera Aldaya discovered that Simultaneous Multithreading (SMT) architectures are vulnerable to side-channel leakage. This issue is known as "PortSmash". (CVE-2018-5407) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.10: libssl1.0.0 1.0.2n-1ubuntu6.1 libssl1.1 1.1.1-1ubuntu2.1 Ubuntu 18.04 LTS: libssl1.0.0 1.0.2n-1ubuntu5.2 libssl1.1 1.1.0g-2ubuntu4.3 Ubuntu 16.04 LTS: libssl1.0.0 1.0.2g-1ubuntu4.14 Ubuntu 14.04 LTS: libssl1.0.0 1.0.1f-1ubuntu2.27 After a standard system update you need to reboot your computer to make all the necessary changes. Due to the low severity of this issue we are not issuing a new release of OpenSSL 1.1.1, 1.1.0 or 1.0.2 at this time. The fix is also available in commit 8abfe72e8c (for 1.1.1), ef11e19d13 (for 1.1.0) and commit 43e6a58d49 (for 1.0.2) in the OpenSSL git repository. As a result of the changes made to mitigate this vulnerability, a new side channel attack was created. The mitigation for this new vulnerability can be found in these commits: 6039651c43 (for 1.1.1), 26d7fce13d (for 1.1.0) and 880d1c76ed (for 1.0.2) References ========== URL for this Security Advisory: https://www.openssl.org/news/secadv/20181030.txt Note: the online version of the advisory may be updated with additional details over time.
