Announcement ID: openSUSE-SU-2019:1792-1 Rating: moderate References: #1097073 #1125740 #1138939 Cross-References: CVE-2019-12904 Affected Products: openSUSE Leap 15.0 ______________________________________________________________________________
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:
- 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:
- Don't run full FIPS self-tests from constructor (bsc#1097073) - Skip all the self-tests except for binary integrity when called from the constructor (bsc#1097073) - Enforce the minimal RSA keygen size in fips mode (bsc#1125740) - avoid executing some tests twice. - Fixed a race condition in initialization. - Fixed env-script-interpreter in cavs_driver.pl - 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.
