TITLE

MySQL MaxDB WebDBM Server Name Service Rejection Vulnerability

DESCRIPTION

MySQL MaxDB before 7.5.00.18 allows remote attackers to cause a denial of service (crash) via an HTTP request to webdbm with high ASCII values in the Server field, which triggers an assert error in the IsAscii7 function. A remotely exploitable denial of service vulnerability exists in MaxDB. This will reportedly trigger an exception due to an assert directive failing, resulting in a denial of service condition in the web agent. This issue was reportedly tested on Windows and Linux versions. Other versions could also be affected. MySQL MaxDB Web Agent WebDBM Server Name Denial of Service Vulnerability iDEFENSE Security Advisory 10.06.04a: www.idefense.com/application/poi/display?id=150&type=vulnerabilities October 6, 2004 I.
