========================================================================== Ubuntu Security Notice USN-4516-1 September 17, 2020
gnupg2 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
Summary:
GnuPG could be made to expose sensitive information.
Software Description: - gnupg2: GNU privacy guard - a free PGP replacement
Details:
It was discovered that GnuPG signatures could be forged when the SHA-1 algorithm is being used. This update removes validating signatures based on SHA-1 that were generated after 2019-01-19. In environments where this is still required, a new option --allow-weak-key-signatures can be used to revert this behaviour.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: gnupg 2.2.4-1ubuntu1.3
In general, a standard system update will make all the necessary changes.
