    descriptionHiroya Ito of GMO Pepabo, Inc. reported that checkpw, a password authentication program, has a flaw in processing account names which contain double dashes. A remote attacker can use this flaw to cause a denial of service (infinite loop). Thanks to Markus Koschany who prepared the Debian package. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
