Summary: mkfontscale produces syscalls with EINVAL https://bugzilla.redhat.com/show_bug.cgi?id=477607 Summary: mkfontscale produces syscalls with EINVAL Product: Fedora Version: 9 Platform: All OS/Version: Linux Status: NEW Severity: medium Priority: low Component: freetype AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] CC: [email protected], [email protected], [email protected] Classification: Fedora Created an attachment (id=327635) --> (https://bugzilla.redhat.com/attachment.cgi?id=327635) patch fixing problems described herein Description of problem: The mkfontscale program uses the freetype library. Our IDS work shows that the freetype library causes mmap syscalls with EINVAL return codes. This is because its not checking the length of the file before calling mmap. If the file is opened readonly and the length is 0, the kernel does not like it. How reproducible: always Steps to Reproduce: 1. add to audit rules: -a always,exit -S mmap -F exit=-ENIVAL -k einval 2. reboot system 3. ausearch --start recent -k einval -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Fedora-fonts-bugs-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/fedora-fonts-bugs-list
