USN-507-1: tcp-wrappers vulnerability

Releases

• Ubuntu 7.04

Packages

• tcp-wrappers -

Details

It was discovered that the TCP wrapper library was incorrectly allowing
connections to services that did not specify server-side connection
details. Remote attackers could connect to services that had been
configured to block such connections. This only affected Ubuntu Feisty.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.04

• libwrap0 - 7.6.dbs-11ubuntu0.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
