Buffer overflow in the diagTasksWebSM command in IBM AIX 5.1, 5.2 and 5.3, might allow local users to execute arbitrary code via long command line arguments.
RC.BOOT in IBM AIX 5.1, 5.2, and 5.3 does not "use a secure location for temporary files," which allows local users to have an unknown impact, probably by overwriting files.
Untrusted execution path vulnerability in chcod on AIX IBM 5.1.0, 5.2.0, and 5.3.0 allows local users to execute arbitrary programs by modifying the PATH environment variable to point to a malicious "grep" program, which is executed from chcod.
Untrusted execution path vulnerability in invscout in IBM AIX 5.1.0, 5.2.0, and 5.3.0 allows local users to gain privileges by modifying the PATH environment variable to point to a malicious "uname" program, which is executed from lsvpd after lsvpd has been invoked by invscout.
Untrusted execution path vulnerability in the diag commands (1) lsmcode, (2) diag_exec, (3) invscout, and (4) invscoutd in AIX 5.1 through 5.3 allows local users to execute arbitrary programs by modifying the DIAGNOSTICS environment variable to point to a malicious Dctrl program.
AIX 4.3.3 through AIX 5.1, when direct remote login is disabled, displays a different message if the password is correct, which allows remote attackers to guess the password via brute force methods.
