Title: IBM AIX lquerypv Local Privilege Escalation Vulnerability
Severity: HIGH
Description:
AIX is a UNIX operating system from IBM. The 'lquerypv' utility is used to examine the properties of physical volume in a volume group on a disk.
AIX is prone to a local privilege-escalation vulnerability because it fails to perform adequate boundary checks on user-supplied data. The issue occurs in the 'lquerypv' utility, which is installed setuid-superuser by default. Specifically, the utility fails to check the length of data passed to the '-V' option before copying it to a fixed-size buffer. When the buffer is passed to the 'sprintf()' function, a stack-based buffer overflow occurs.
Attackers can exploit this issue to execute arbitrary code using superuser privileges. Successful exploits will completely compromise affected computers.
Affected Products:
- IBM AIX 5.2
- IBM AIX 5.3
