InfoSect's Month of Pointless Bugs (#12)

Dr Silvio Cesare

InfoSect, Canberra's hackerspace, regularly runs public group sessions to perform code review and vulnerability discovery. Over the next 30 days, I'll highlight the source code of 30 unknown vulnerabilities.

Bug #12

In the slashem game, the code doesn't check the return value of setuid/setgid. Similar to http://blog.infosectcbr.com.au/2018/02/infosects-month-of-pointless-bugs-3.html

sys/unix/unixmain.c

# ifdef SECURE (void) setgid(getgid()); (void) setuid(getuid()); /* Ron Wessels */ # endif
