![]() The emitted code would then have to call the following in case of a detected stack smash: * Not necessary, assuming %p doesn't spit out extra characters.*/įail (msg2, strlen (msg2), "stack smashing detected: terminated") + strlen (srcfile) + sizeof(void*)*2 + 17 Int msg2len = strlen (msg) + strlen (fctn) *Allocate: "%s %s:%s (damage: 0x%p) ",msg,srcfile,fctn,damage*/ ![]() _stack_chk_fail2 (char *fctn, char *srcfile, void *damage)Ĭonst char *msg = "*** stack smashing detected ***:" The only way to allow old behavior is to add ANOTHER external function to libssp. Unfortunately it seems this now can't be (cleanly) fixed without breaking existing stack smash protected code. usr/lib/foxsrt/test/ssp_smash terminated *** Stack smashing detected in function vuln() in source file net.c!!! AbortedĮxamining the current source, the following code exists:Ĭonst char *msg = "*** stack smashing detected ***: " įail (msg, strlen (msg), "stack smashing detected: terminated") ![]() In the original ProPolice that the gcc 4.1 stack smash protection was derived from, a stack smash would illicit a message similar to: ![]()
