I've spent some time on debugging, here are results: 1) this happens due to buffer overflow inside vt(4) - internal variable vt_draw_logo_cpus gets non-zero value, this why we see those logos. 2) i'm not sure about security issues with this problem, thus i'll post mail to secteam@ before revealing the fix. -- You are receiving this mail because: You are the assignee for the bug.help
