347090 - crash if no read permissions on fonts /usr/libexec/mozilla-launcher: line 117: 24067 Segmentation fault

Status: RESOLVED DUPLICATE of bug 183729

(Core Graveyard :: GFX: Gtk, defect)

Description

[nbargnesi]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.0.5) Gecko/20060802 Firefox/1.5.0.5
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.0.5) Gecko/20060802 Firefox/1.5.0.5

If Firefox tries to access a font that has no read permissions, a segfault occurs.

The following is from running Firefox from a terminal:

No running windows found
/usr/libexec/mozilla-launcher: line 117: 24067 Segmentation fault      "$mozbin" "$@"
firefox-bin exited with non-zero status (139)

I am attaching strace and gdb output/stack trace.

Reproducible: Always

Steps to Reproduce:
1.  Make some key fonts contain no read permissions for the user who will run Firefox.  (I used chmod o-r /usr/share/fonts/truetype/arial.ttf)
2.  Run Firefox, google.com should crash the browser.  I'm guessing any requested font that has no read permissions will cause the crash.
3.  

Actual Results:  
Firefox segfaults with the strace and backtrace contained in the details.

Expected Results:  
ensured it could read the font first i think

this is already reported.

note that to my knowledge mozilla.org does not ship a "mozilla-launcher" so you should have reported your problem to your linux vendor. unfortunately you didn't indicate which that is.

you need a build with symbols. if you can't get one from your distribution, then you can install a mozilla.org release and let talkback correlate symbols once it reports the crash to the database.

about:buildconfig shows the Linux vendor - Gentoo

as bug 183729 and bug 180309.  I don't know of anything more recent.

with gentoo, you get to build with symbols yourself.
