SuSE default package: no
Other affected systems: all unix systems using inn <= 2.2.1


A security hole was discovered in the package mentioned above. Please update as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s).

Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue.

Please note, that that we provide this information on an "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package.


1. Problem Description

The Inter Net News server inn does not do proper bounds checking.

2. Impact

The daemon could be crashed remotely by overflowing the static buffers.

3. Solution

Update the package from our FTP server. The fixed inn package for 6.3-AXP is included in the SuSE-AXP distribution. Our maintainer of inn tries to build a RPM for 5.3, which will as soon as possible be available if everything goes well.
