SEGV should sem_open fail in locks/unix/proc_mutex.c

           Summary: SEGV should sem_open fail in locks/unix/proc_mutex.c
           Product: APR
           Version: HEAD
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: APR
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: sherod@pillardata.com


In httpd-2.0.44 if the sem_open function on line 120 of unix/proc_mutex.c 
fails, the clean-up that occurs from the call on line 124 of the same file 
will fail since the semaphore (psem) is not a valid file descriptor.  The 
error actually is in line 82 of the same file in the sem_close() call.  (In 
fact, the mutex filedes will contain nonsense which might do unforeseen evil 
things later.) 
 
A simple fix would be to insert at line 124 of unix/proc_mutex.c: 
 
new_mutex->interproc->filedes = -1;
