Subject: mc 4.8.19: segfaults while searching for contents
Date: Tue, 03 Oct 2017 08:50:21 +0200	[thread overview]
Message-ID: <821fb18a-1394-ea3d-933d-72c8ec2ee2d3@ipfire.org> (raw)

Hi,

Suddenly 'mc 4.8.19' starts throwing segfaults each time I search for contents in multiple files, e.g. in a directory structure like '/usr/local/bin'. Searching in SINGLE files or in a directory which contains only *.sh-files is ok):

...
07:42:32	kernel: 	mc[17515]: segfault at a39349a0 ip a2fbdf81 sp b0f41af4 error 4 in libpcre.so.1.2.9[a2f94000+44000]
07:42:32	kernel: 	grsec: From 192.168.100.1: Segmentation fault occurred at a39349a0 in /usr/bin/m c[mc:17515] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:16795] uid/euid:0/0 gid/egid:0/0
07:42:32	kernel: 	grsec: From 192.168.100.1: denied resource overstep by requesting 4096 for RLIMIT_CORE against limit 0 for /usr/bin/mc[mc:17515] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:16795] uid/euid:0/0 gid/egid:0/0
...

The same happens on a fresh test installation.

Right now I'm  thinking about using 'paxctl' on '/usr/bin/mc', but I'm not really sure...:

1. If this would be a solution
2. Which options to use - and
3. On which parts ('/usr/bin/mc'?) exactly.

I'm testing with:

...
paxctl -cm /usr/bin/mc
...

But had no luck until now.

Anybody got a hint or experiencing the same?

Best,
Matthias
