MySQL: Two Denial of Service vulnerabilities

MySQL: Two Denial of Service vulnerabilities Two Denial of Service vulnerabilities have been discovered in MySQL. MySQL 2007-05-08 2007-05-08 170126 171934 remote 5.0.38 5.0 5.0.38

MySQL is a popular multi-threaded, multi-user SQL server.

mu-b discovered a NULL pointer dereference in item_cmpfunc.cc when processing certain types of SQL requests. Sec Consult also discovered another NULL pointer dereference when sorting certain types of queries on the database metadata.

In both cases, a remote attacker could send a specially crafted SQL request to the server, possibly resulting in a server crash. Note that the attacker needs the ability to execute SELECT queries.

There is no known workaround at this time.

All MySQL users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mysql-5.0.38"
