Vulnerability Note VU#118277

The Oracle Internet Directory LDAP (oidldapd) contains buffer overflow

Original Release date: 12 Jul 2001 | Last revised: 12 Jul 2001


Oracle Internet Directory version 2.0.6, which ships with Oracle version 8i for Linux (8.1.6), contains a program, oidldapd, that is an LDAP Daemon. There is a buffer overflow in the LDAP Daemon that allows a local user to obtain the euid of the oidldapd process, typically user oracle.


There is a buffer overflow in the oidldapd with regard to the "connect" option. Since oidldapd typically runs as user oracle, this vulnerability can be used by local users to obtain euid of user oracle. As a result of the default installation, user oracle owns all database files. An exploit has been published.


All database files can be edited/deleted by a malicious user. A local user can obtain privileges of the oidldapd process, typically oracle.


Oracle encourages all Linux directory developers to upgrade to Oracle Internet Directory, v2.1.1, part of the Oracle 8.1.7 (8i Release 3) server media pack, from

If you use a UFS filesystem, use chmod to set the file permissions to 710 for the oidldapd and oidmon executables. For other filesystems (e.g. AFS) use equivalent settings to restrict access to privileged users only.
