[ASA-201812-7] lib32-openssl-1.0: private key recovery
Arch Linux Security Advisory ASA-201812-7 ========================================= Severity: Low Date : 2018-12-08 CVE-ID : CVE-2018-0734 CVE-2018-5407 Package : lib32-openssl-1.0 Type : private key recovery Remote : Yes Link : https://security.archlinux.org/AVG-806 Summary ======= The package lib32-openssl-1.0 before version 1.0.2.q-1 is vulnerable to private key recovery. Resolution ========== Upgrade to 1.0.2.q-1. # pacman -Syu "lib32-openssl-1.0>=1.0.2.q-1" The problems have been fixed upstream in version 1.0.2.q. 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-2018-5407 (private key recovery) A vulnerability has been found in the ECC scalar multiplication implementation of OpenSSL < 1.1.0i and <= 1.0.2p. The implementation, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key. Impact ====== A remote attacker might be able to recover a private DSA key via a timing attack. In addition, a local attacker might be able to recover a private ECC key via a timing attack.
