CVE-2008-1601: Stack-based buffer overflow in the reboot program on IBM AIX 5.2 and 5.3 allows local users in the shutdown...

Security readout for executives and security teams

This is a local privilege escalation issue in IBM AIX 5.2 and 5.3. A user already placed in the shutdown group could abuse a stack buffer overflow in the reboot program to gain additional privileges. It is not described as remotely exploitable in the provided sources. Exposure is most likely on legacy IBM AIX 5.2 or 5.3 systems where non-administrative users have local access and shutdown group membership. Internet-facing exposure is not indicated by the provided sources. Treat this as a legacy-system privilege escalation risk. It is not described as remotely exploited, but affected AIX hosts with shared local access should be reviewed promptly because privilege boundaries may be bypassed. Mitigation focus: Check IBM APAR guidance for IZ15479 and IZ15480.; Inventory AIX 5.2 and 5.3 systems.; Restrict shutdown group membership to required administrators only..
