Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in OpenSSL. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools - openssl1.0: Secure Socket Layer (SSL) cryptographic library and tools Details: Samuel Weiser discovered that OpenSSL incorrectly handled DSA signing. An attacker could possibly use this issue to perform a timing side-channel attack and recover private DSA keys. (CVE-2018-0734) Samuel Weiser discovered that OpenSSL incorrectly handled ECDSA signing. An attacker could possibly use this issue to perform a timing side-channel attack and recover private ECDSA keys. 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". An attacker could possibly use this issue to perform a timing side-channel attack and recover private keys. (CVE-2018-5407) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.10: Ubuntu 18.04 LTS: Ubuntu 16.04 LTS: Ubuntu 14.04 LTS: After a standard system update you need to reboot your computer to make all the necessary changes.
