Debian Lenny DSA-2057-1 Critical: MySQL Remote DoS and Buffer Overflow

Several vulnerabilities have been discovered in the MySQL
database server.
The Common Vulnerabilities and Exposures project identifies the
following problems:


CVE-2010-1626

MySQL allows local users to delete the data and index files of another
user's MyISAM table via a symlink attack in conjunction with the DROP
TABLE command.


CVE-2010-1848

MySQL was susceptible to a buffer-overflow attack due to a
failure to perform bounds checki...
