Title Non-root user able to run root owned program without setuid bit set
Ref. No. QNX.000000423
Category(ies) Development
Issue We have upgraded our system from QNX 4.23A to QNX 4.24 and now non-root users are able to run root owned programs, as root, when the setuid bit is not set.
Solution This was a bug introduced in version 4.24 which allowed non-root users to run programs which were owned by root, to run as root, without the setuid bit set.  This bug is fixed in version 4.25.
