[Bug 342717] Re: fc-cache segfaults when scanning an italic BDF font with empty SETWIDTH_NAME
Related to the security issue, I don't know if the attached font is segfaulting for the same reason, but I had a session ending segfault when running fc-cache -fv. I went through the ~3000 custom fonts I have, and this is the only one I could find that segfaults. Though oddly, the segfault only killed my gnome-session the first time. I don't know if it's a fontconfig issue or a gnome issue, but with the font in a font load path other gnome issues occur as well: If gnome is locked, the unlock dialog won't appear. If no session exists and you try to login, the login seems to succeed, but the desktop never loads. Removing the font resolves these issues. Running fontconfig version 2.11.0 on Trusty. ** Attachment added: "Font that causes a segfault when running fc-cache -fv" https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/342717/+attachment/3934285/+files/ahronbd.ttf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/342717 Title: fc-cache segfaults when scanning an italic BDF font with empty SETWIDTH_NAME To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/342717/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Still segfaults in 10.04 LTS, but doesn't take down the whole session. ** This bug is no longer flagged as a security vulnerability -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/342717 Title: fc-cache segfaults when scanning an italic BDF font with empty SETWIDTH_NAME -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
