Open source database company MySQL issued a security update to address flaws in its product that could open up users to attack. Rated a "moderate risk" vulnerability by FrSIRT, one of the flaws involves a buffer overflow that could allow for code execution, while the other two involve a validation error, and could expose information within system memory.
The issue affects MySQL versions 4.0.26, 4.1.18. 5.0.20 and 5.1.9, as well as prior versions of those major releases. The most recent version, MySQL 5.0, was released last fall and has seen quick adoption among users of the open source database software.
