Synopsis


Two Denial of Service vulnerabilities have been discovered in MySQL.

Background


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

Affected packages



Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-db/mysql < 5.0.38 >= 5.0.38 < 5.0

Description


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.

Impact


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.

Workaround


There is no known workaround at this time.

Resolution


All MySQL users should upgrade to the latest version:

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