Description Hanno Böck gentoo-dev 2017-06-20 19:06:43 UTC
Found by project zero:

Upstream version 5.5.5 contains the fix. We may have to check what other apps bundle unrar (e.g. clamav).
Comment 1 Thomas Deutschmann gentoo-dev 2017-06-21 11:48:57 UTC
Now in repository via

UnRAR v5.5.5 is RAR 5.50 beta 4 so app-arch/rar is probably affected as well.

@ Arches,

please test and mark stable: =app-arch/unrar-5.5.5

Comment 5 Thomas Deutschmann gentoo-dev 2017-06-21 13:27:30 UTC
