IBM AIX chpath, rmpath, and devinstall commands buffer overflow
| aix-chpath-rmpath-devinstall-bo (35971) |  High Risk |
Description:
IBM AIX is vulnerable to a buffer overflow, caused by improper bounds checking by the chpath, rmpath, and devinstall commands. By sending a specially-crafted command-line argument, a local attacker with system group privileges could overflow a buffer and execute arbitrary code on the system with root privileges.
Platforms Affected:
- IBM, AIX 5.2
- IBM, AIX 5.3
Remedy:
For AIX 5.2.0:
Apply APAR IZ00531, available from the IBM Quick Links Web site. See References.
For AIX 5.3.0:
Apply APAR IZ01433, available from the IBM Quick Links Web site. See References.
--OR--
Apply the interim fix for this vulnerability (cmdcfg_ifix.tar.Z), available from the IBM AIX FTP site. See References.
Consequences:
Gain Privileges
