Problem description

Two vulnerabilites to denial of service in the open-iscsi daemon have been found. The daemon does not properly check the credentials of the process connecting to the management interface, which could be abused by an attacker to disrupt iSCSI connections. Likewise, a semaphore for a shared memory segment of the logging mechanism has too broad permissions, which allows local users to block the daemon on the next attempt to log an event.
These DoS vulnerabilities are tracked by CVE-2007-3099 and CVE-2007-3100.
