Subject: [PATCH] Fix bug-regex4
Date: Mon, 07 Apr 2003 21:13:00 -0000 [thread overview]
Message-ID: <20030407211308.GX16629@sunsite.ms.mff.cuni.cz> (raw)
Hi!
If range and/or stop arguments to re_search_2 are too large, re_search_2
might search beyond end of buffer.
2003-04-07 Jakub Jelinek <jakub@redhat.com>
* posix/bug-regex4.c (main): Cap range and stop arguments to
sum of size1 and size2 arguments.
