IBM AIX RDIST buffer overflow
| aix-rdist-bo (32184) |  High Risk |
Description:
IBM AIX is vulnerable to a buffer overflow, caused by improper bounds checking by the RDIST command in bos.rte.libc. By sending a specially-crafted RDIST command, a local attacker could overflow a buffer and execute arbitrary code on the system with unspecified setuid privileges.
