Gentoo Linux Security Advisory

Title: MySQL: Denial of Service (GLSA 200608-09)
Severity: normal
Exploitable: remote
Date: August 06, 2006
Updated: August 07, 2006
Bug(s): #142429
ID: 200608-09

Synopsis

An authenticated user can crash MySQL through invalid parameters to the date_format function.

Background

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

Affected Packages

Package: dev-db/mysql
Vulnerable: < 4.1.21
Unaffected: >= 4.1.21
Unaffected: < 4.1.0
Architectures: All supported architectures


Description

Jean-David Maillefer discovered a format string vulnerability in time.cc where MySQL fails to properly handle specially formatted user input to the date_format function.

Impact

By specifying a format string as the first parameter to the date_format function, an authenticated attacker could cause MySQL to crash, resulting in a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All MySQL users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --verbose --oneshot ">=dev-db/mysql-4.1.21"


References

CVE-2006-3469
