Multiple vulnerabilities have been identified affecting MySQL, a relational database server, and its associated interactive client application. The Common Vulnerabilities and Exposures project identifies the following two problems: Kay Roepke reported that the MySQL server would not properly handle an empty bit-string literal in an SQL statement, allowing an authenticated remote attacker to cause a denial of service (a crash) in mysqld. This issue affects the oldstable distribution (etch), but not the stable distribution (lenny). Thomas Henlich reported that the MySQL commandline client application did not encode HTML special characters when run in HTML output mode (that is, "mysql --html ..."). This could potentially lead to cross-site scripting or unintended script privilege escalation if the resulting output is viewed in a browser or incorporated into a web site.
