bug1

QA REPRODUCER:

convert bug1 /dev/null

should not crash

valgrind convert bug1 /dev/null

should not show out of bounds reads

(NOTE: can not reproduce currently)
Comment 2 Marcus Meissner 2017-03-06 10:12:26 UTC
We have several patches touching this code already in ImageMagick, one of them probably has fixed it already.

similar to CVE-2016-7518 in bug 1000694.


GraphicsMagic in SLE11 seems to still have the buggy code.
Comment 3 Marcus Meissner 2017-03-06 10:12:46 UTC
QA REPRODUCER (GraphicsMagick):

gm convert bug1 /dev/null

Comment 7 Petr Gajdos 2017-03-21 13:15:51 UTC
I get no crash nor valgrind errors anywhere.
Comment 9 Petr Gajdos 2017-03-21 15:47:07 UTC
I bet the bug does not affect GraphicsMagick:

bytes_per_line += sun_info.width % 8 ? 1 : 0;
Comment 11 Swamp Workflow Management 2017-03-29 04:10:24 UTC
SUSE-RU-2017:0843-1: An update that has two recommended fixes can now be installed.
