Package: gv
Version: 1:3.7.4-1
Severity: normal
File: /usr/bin/gv
With the foo.ps below running
gv foo.ps
gets a segfault. The blank line in foo.ps seems to matter. If you take
it away then gv doesn't segv.
I struck this in some output from an "lsys" program. This foo.ps is an
extremely cut down version of its output. I have no idea if this or the
original are correct postscript. Perhaps not. I hoped that if not then
it would provoke an error message of some sort rather than a segv.
Building with noopt and under gdb suggests the offending part may be
__strlen_ia32 () at ../sysdeps/i386/i686/multiarch/../../i586/strlen.S:98
98 ../sysdeps/i386/i686/multiarch/../../i586/strlen.S: No such file or
directory.
(gdb) where
#0 __strlen_ia32 () at ../sysdeps/i386/i686/multiarch/../../i586/strlen.S:98
#1 0x0806ba3f in setup_ghostview () at misc.c:999
#2 0x080686c9 in main (argc=2, argv=0xbffff914) at main.c:1238
with misc.c:999
maxlen = max(maxlen, (int)strlen(doc->pages[i].label));
i==0 and doc->pages[i].label == NULL, so strlen(NULL) faulting. Should
it watch out for structured but dodgy documents leaving label=NULL?
