Description Lars Wendler (Polynomial-C) (RETIRED) gentoo-dev 2016-03-07 21:21:19 UTC
From URL:

Alexander Cherepanov discovered that the glob implementation in glibc does not correctly handle overlong names in struct dirent buffers when GLOB_ALTDIRFUNC is used.
Comment 1 Agostino Sarubbo gentoo-dev 2016-03-08 15:10:17 UTC
Unless I'm missing something the whiteboard is just upstream.
Comment 2 SpanKY gentoo-dev 2016-11-12 06:27:23 UTC
should be fixed in glibc-2.23-r3.  will need some time to bake in ~arch.
Comment 3 Thomas Deutschmann (RETIRED) gentoo-dev 2016-12-13 14:11:17 UTC
@ Maintainer(s): One month later, can we now stabilize =sys-libs/glibc-2.23-r3?
Comment 4 SpanKY gentoo-dev 2016-12-14 16:28:11 UTC
i don't think we need to rush this.  wait until the end of Dec and it should be fine if there are no new issues.
