Multiple vulnerabilities have been reported in IBM AIX, which can be exploited by malicious, local users to delete certain system files, cause a DoS (Denial of Service), or gain escalated privileges.

1) Boundary errors within fcstat, ibstat, mkpath, svprint, swcons, uucp UNIX-to-UNIX Copy, and xlplm commands can be exploited to cause buffer overflows.

Successful exploitation allows execution of arbitrary code with root privileges.

2) User privileges are not being checked by the perfstat system call in perfstat kernel extension for SET operations and can be exploited to e.g. cause the system to hang.

3) An input validation error in the invscout command can be exploited to e.g. delete certain system files.
