Arch Linux Security Advisory ASA-201812-5 ========================================= Severity: Low Date : 2018-12-08 CVE-ID : CVE-2018-0734 CVE-2018-0735 Package : openssl Type : private key recovery Remote : Yes Link : https://security.archlinux.org/AVG-792 Summary ======= The package openssl before version 1.1.1.a-1 is vulnerable to private key recovery. Resolution ========== Upgrade to 1.1.1.a-1. # pacman -Syu "openssl>=1.1.1.a-1" The problems have been fixed upstream in version 1.1.1.a. Workaround ========== None. Description =========== - CVE-2018-0734 (private key recovery) A timing vulnerability has been found in DSA signature generation in openssl versions up to and including 1.1.1, where information is leaked via a side channel when a BN is resized and could lead to private key recovery. - CVE-2018-0735 (private key recovery) The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side channel attack in openssl versions prior to 1.1.1a. An attacker could use variations in the signing algorithm to recover the private key. Impact ====== A remote attacker might be able to recover a private ECDSA or DSA key via a timing attack.
