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 Desktop Packages, which is subscribed to fontconfig in Ubuntu. https://bugs.launchpad.net/bugs/342717 Title: fc-cache segfaults when scanning an italic BDF font with empty SETWIDTH_NAME Status in “fontconfig” package in Ubuntu: Confirmed Bug description: Binary package hint: fontconfig Steps to reproduce: 1. Save the attached .bdf font into an empty, temporary directory. 2. Run the following command: fc-cache . Expected results: - fc-cache scans the directory, finds no usable fonts, quits cleanly. Actual results: - Segmentation fault. Notes: Deleting either of the properties in the font prevents the crash, as does changing the value of "SETWIDTH_NAME" to be non-empty.
