A flaw in IBM"s Lotus Domino Server could be used to crash systems, a security company has warned, but Big Blue is shrugging off the report.
The denial-of-service vulnerability appears in versions 6.5.1 and 6.0.3 of the e-mail and calendar server software, security company iDefense said in an advisory released Wednesday. "Exploitation of this vulnerability allows unauthenticated remote attackers to crash the Web service, thereby preventing legitimate usage," iDefense said in the advisory. "This attack requires minimal resources to launch and can be repeated to ensure that an unpatched computer is unable to recover."
