Title: Red Hat Directory Server Accept Language HTTP Headers Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
Red Hat Directory Server is a centralization server based on the Lightweight Directory Access Protocol (LDAP).
The server is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. The problem occurs in the Accept Language HTTP header parser in the 'adminutil' library used in the Administration Server's CGI scripts. A remote attacker who can connect to the administration server web interface may be able to exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause denial-of-service conditions.
NOTE: The Administration Server of Directory Server usually runs with superuser privileges.
The following are affected:
- Red Hat Directory Server 7.1
- Versions prior to 'adminutil' 1.1.7
Affected Products:
- HP HP-UX 11.11.0
