It is recommended that administrators running libgcrypt check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- SUSE Security Update: Security update for libgcrypt ______________________________________________________________________________ Announcement ID: SUSE-SU-2019:1859-1 Rating: moderate References: #1097073 #1125740 #1138939 Cross-References: CVE-2019-12904 Affected Products: SUSE Linux Enterprise Module for Open Buildservice Development Tools 15 SUSE Linux Enterprise Module for Basesystem 15 ______________________________________________________________________________ An update that solves one vulnerability and has two fixes is now available. Description: This update for libgcrypt fixes the following issues: Security issues fixed: o CVE-2019-12904: The C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) (bsc#1138939) Other bugfixes: o Don't run full FIPS self-tests from constructor (bsc#1097073) o Skip all the self-tests except for binary integrity when called from the constructor (bsc#1097073) o Enforce the minimal RSA keygen size in fips mode (bsc#1125740) o avoid executing some tests twice. o Fixed a race condition in initialization. o Fixed env-script-interpreter in cavs_driver.pl o Fixed redundant fips tests in some situations causing failure to boot in fips mode. (bsc#1097073) This helps during booting of the system in FIPS mode with insufficient entropy. Patch Instructions: To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
