IBM AIX lqueryvg utility sprintf function buffer overflow
| aix-lqueryvg-sprintf-bo (38165) |  High Risk |
Description:
The IBM AIX lqueryvg utility is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the sprintf function. By sending an overly long parameter using the -p command line option, a local attacker 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 IZ05349, available from the IBM Quick Links Web site. See References.
For AIX 5.3.0:
Apply APAR IZ05129, available from the IBM Quick Links Web site. See References.
--OR--
Apply the interim fix for this vulnerability (lqueryvg_ifix.tar), available from the IBM AIX FTP site. See References.
Consequences:
Gain Privileges
