Comment 1 John Helmert III gentoo-dev Security 2020-08-28 20:58:16 UTC
These are ostensibly against an rc version and I can't reproduce with 2.15.04 so we might not be affected.

Sorry, 2.14.02 is what appears unaffected.

It's not clear if you ping maintainers or security. If not specified otherwise I always assume assignee.

It's also not clear what action you expect.

Upstream bugs claim to fix both in problems in >=nasm-2.15.04.

Sorry! It is unclear whether our versions in tree were ever affected. If not, we can just close this bug.

nasm-2.15.03 was probably last affected version (not in tree anymore).
