TITLE

OpenSSL CVE-2018-5407 Side Channel Attack Information Disclosure Vulnerability

DESCRIPTION

Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'. 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. This vulnerability stems from configuration errors in network systems or products during operation. Solution: For information on upgrading Ansible Tower, reference the Ansible Tower Upgrade and Migration Guide: https://docs.ansible.com/ansible-tower/latest/html/upgrade-migration-guide/ index.html 4. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201903-10 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: OpenSSL: Multiple vulnerabilities Date: March 14, 2019 Bugs: #673056, #678564 ID: 201903-10 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple Information Disclosure vulnerabilities in OpenSSL allow attackers to obtain sensitive information. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/openssl < 1.0.2r >= 1.0.2r Description =========== Multiple vulnerabilities have been discovered in OpenSSL. Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker to obtain sensitive information, caused by the failure to immediately close the TCP connection after the hosts encounter a zero-length record with valid padding. A local attacker could run a malicious process next to legitimate processes using the architectureas parallel thread running capabilities to leak encrypted data from the CPU's internal processes. Workaround ========== There is no known workaround at this time. Resolution ========== All OpenSSL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.2r" References ========== [ 1 ] CVE-2018-5407 https://nvd.nist.gov/vuln/detail/CVE-2018-5407 [ 2 ] CVE-2019-1559 https://nvd.nist.gov/vuln/detail/CVE-2019-1559 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201903-10 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.

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: 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
