Buffer overflow in multiple "p" commands in IBM AIX 5.1, 5.2 and 5.3 might allow local users to execute arbitrary code via long command line arguments to (1) penable or other hard-linked files including (2) pdisable, (3) pstart, (4) phold, (5) pdelay, or (6) pshare.

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.

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 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.

Buffer overflow in paginit in AIX 5.1 through 5.3 allows local users to execute arbitrary code via a long username.

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.
