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 | Architecture(s) |
|---|---|---|---|
| dev-db/mysql | < 5.0.38 | >= 5.0.38 | All supported architectures |
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"
