https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D204643 --- Comment #3 from Kristof Provost <kp@freebsd.org> --- Created attachment 168071 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D168071&action= =3Dedit msdosfs: Prevent buffer overflow when expanding win95 names My initial analysis seems to have missed a different overflow, in win2unixf= n(). It looks like dos2unixfn() is probably safe, because it's unlikely that an expansion of 8 or 12 bytes will take more than 255 bytes. Can you test the attached patch? It should fix the panic you're seeing. --=20 You are receiving this mail because: You are the assignee for the bug.=
