            | 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. |  |
