Description Hanno Böck gentoo-dev 2017-06-20 19:06:43 UTC 
Found by project zero:
https://bugs.chromium.org/p/project-zero/issues/detail?id=1286&can=1&q=unrar&desc=6

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 (RETIRED) gentoo-dev 2017-06-21 11:48:57 UTC 
Now in repository via https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=dabe9845e2f4b38d214b8cc1e27f0a43680eb39c

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 2 Agostino Sarubbo gentoo-dev 2017-06-21 12:10:08 UTC 
amd64 stable
Comment 3 Agostino Sarubbo gentoo-dev 2017-06-21 12:12:23 UTC 
x86 stable.

Maintainer(s), please cleanup.
Security, please add it to the existing request, or file a new one.
Comment 4 Thomas Deutschmann (RETIRED) gentoo-dev 2017-06-21 12:22:49 UTC 
Repository is now clean (https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f84896cce4b495bcf147fd493e815d5106f7aa76).

New GLSA request filed.
Comment 5 Thomas Deutschmann (RETIRED) gentoo-dev 2017-06-21 13:27:30 UTC 
Oops, we need more than just amd64/x86 -- mixed with app-arch/rar.


@ Arches,

please test and mark stable: =app-arch/unrar-5.5.5
Comment 6 Thomas Deutschmann (RETIRED) gentoo-dev 2017-06-21 15:12:14 UTC
