I confirm that perl-Convert-ASN1-0.27-16.el8.noarch is vulnerable.

Comment 3 Philipp Trulson 2020-05-14 13:05:01 UTC

Did this package get removed because of the vulnerability? 
This is blocking the installation of nagios-plugins-all-2.3.3-1.el8.x86_64 which depends on nagios-plugins-ssl_validity-2.3.3-1.el8.x86_64 which depends on perl-Crypt-X509-0.51-19.el8.noarch which depends on perl(Convert::ASN1) >= 0.19. We really need this package back ASAP.

Comment 4 Petr Pisar 2020-05-14 13:21:54 UTC

This package was removed from EPEL. But for a different reason. This package was added into RHEL 8.2 and thus removed from EPEL because EPEL cannot provide the same packages (bug #1833568).

Comment 5 Paul Howarth 2020-05-15 12:02:51 UTC

Whilst you wait for CentOS 8.2 to be released, you can find the old EPEL package here:

Comment 6 Philipp Trulson 2020-05-15 15:31:11 UTC

Thanks for this info Paul! The same thing already happened with zstd, it's a pity that this breaks so many dependent programs on CentOS.
