Buffer overflow in the chcons (chcon) command in IBM AIX 5.2 and 5.3, when DEBUG MALLOC is enabled, might allow attackers to execute arbitrary code via a long command line argument.

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.

Buffer overflow in the PerlIO implementation in Perl 5.8.0, when installed with setuid support (sperl), allows local users to execute arbitrary code by setting the PERLIO_DEBUG variable and executing a Perl script whose full pathname contains a long directory tree.

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.

Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.

Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.
