The Apache Software Foundation has updated its popular Web server software to guard against a serious, as yet unspecified, denial of service risk.

Users of version 2.x of the Web server on all platforms are urged to upgrade to version 2.0.45. Sites running 1.x aren't affected.

An advisory, published by BugTraq, is to be made available at this time. According to the limited information so far published, the flaw is yet to be exploited.

Information of the upgrade is available from the Apache Software Foundation here. Upgrading to 2.0.45 will fail to help the small number of users running Apache on OS/2.

Nonetheless the fix is deemed too important to wait resolution of the issue in these limited cases.

Version 2.0.45 is also designed to address a number of less bugs, as explained in greater detail here. ®
