I was just about to type "make installworld" when I got this message I checked the commit logs and didn't see any recent commits that looked suspicious, and since I do have a serial console I decided to throw caution to the wind and give the new kernel a try. Other than an annoyingly long pause while GEOM waits for my SCSI cdrom drive to figure out that it is empty (which has been noted in another thread), my system booted without any problems. My kernel has everything commited to the present time except: tjr 2003/10/11 21:25:26 PDT FreeBSD src repository Modified files: sys/i386/ibcs2 ibcs2_misc.c ibcs2_signal.c ibcs2_socksys.c ibcs2_util.c ibcs2_util.h imgact_coff.c Log: Fix a multitude of security bugs in the iBCS2 emulator: - Return NULL instead of returning memory outside of the stackgap in stackgap_alloc() (FreeBSD-SA-00:42.linux) - Check for stackgap_alloc() returning NULL in ibcs2_emul_find(); other calls to stackgap_alloc() have not been changed since they are small fixed-size allocations. - Replace use of strcpy() with strlcpy() in exec_coff_imgact() to avoid buffer overflow - Use strlcat() instead of strcat() to avoid a one byte buffer overflow in ibcs2_setipdomainname() - Use copyinstr() instead of copyin() in ibcs2_setipdomainname() to ensure that the string is null-terminated - Avoid integer overflow in ibcs2_setgroups() and ibcs2_setgroups() by checking that gidsetsize argument is non-negative and no larger than NGROUPS_MAX. - Range-check signal numbers in ibcs2_wait(), ibcs2_sigaction(), ibcs2_sigsys() and ibcs2_kill() to avoid accessing array past the end (or before the start) Revision Changes Path 1.52 +21 -3 src/sys/i386/ibcs2/ibcs2_misc.c 1.32 +7 -2 src/sys/i386/ibcs2/ibcs2_signal.c 1.19 +5 -3 src/sys/i386/ibcs2/ibcs2_socksys.c 1.17 +4 -2 src/sys/i386/ibcs2/ibcs2_util.c 1.17 +4 -1 src/sys/i386/ibcs2/ibcs2_util.h 1.61 +1 -1 src/sys/i386/ibcs2/imgact_coff.c Maybe this problem only affects certain hardware.
