medium Nessus Plugin ID 126976

Language:

Synopsis

The remote openSUSE host is missing a security update.

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.

This update was imported from the SUSE:SLE-15:Update update project.

Solution

Update the affected libgcrypt packages.
