Description Sam James archtester gentoo-dev Security 2020-04-25 22:57:53 UTC
"The email-ingestion feature in Best Practical Request Tracker 4.1.13 through 4.4 allows denial of service by remote attackers via an algorithmic complexity attack on email address parsing."
Comment 1 Sam James archtester gentoo-dev Security 2020-04-25 22:58:52 UTC
This seems to actually be a bug in Email-Address-List. Debian have tracked down the patches but 0.6 is fixed anyway.

So, @maintainer(s), please cleanup =dev-perl/Email-Address-List-0.50.0.
