(SeaMonkey :: General, defect)

Description

[Pierre Poissinger]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040817 Firefox/0.9.3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040817 Firefox/0.9.3

if the access to a specific font is restricted (no read) to the user launching
the browser, mozilla will seg fault during the page load... this affects firefox too

At least with true type fonts...

Reproducible: Always
Steps to Reproduce:
1. Change access of verdana.ttf (in fonts dir) to a non readable prop for a
normal user
2. launch with this user moz and try to load a page...


Actual Results:  
Seg fault....
output from strace on mozilla
open("/usr/X11R6/lib/X11/fonts/TrueType/verdana.ttf", O_RDONLY) = -1 EACCES
(Permission denied)
open("/usr/X11R6/lib/X11/fonts/TrueType/verdana.ttf", O_RDONLY) = -1 EACCES
(Permission denied)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
unlink("/home/muaddib/.mozilla/default/pp3druwu.slt/lock") = 0
rt_sigaction(SIGSEGV, {SIG_DFL}, NULL, 8) = 0
rt_sigprocmask(SIG_UNBLOCK, [SEGV], NULL, 8) = 0
kill(26914, SIGSEGV)                    = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++


Expected Results:  
at least, moz should load a fail-over fonts or give a nice msg why he
crashs...seg fault are not so clear
;)
