Security Advisory - RHSA-2002:196-19
-------------------------------------------------------------------------------
Summary:
Updated xinetd packages fix denial of service vulnerability

Xinetd contains a denial-of-service (DoS) vulnerability.

UPDATE 2002-12-02: Updated packages are available to fix issues encountered
with the previous errata packages.

Description:
Xinetd is a secure replacement for inetd, the Internet services daemon.

Versions of Xinetd prior to 2.3.7 leak file descriptors for the signal
pipe to services that are launched by xinetd. This could allow an attacker
to execute a DoS attack via the pipe. The Common Vulnerabilities and
Exposures project has assigned the name CAN-2002-0871 to this issue.

Red Hat Linux 7.3 shipped with xinetd version 2.3.4 and is therefore
vulnerable to this issue.  All users are advised to upgrade to the errata
packages which fix the vulnerability.

Thanks to Solar Designer for discovering this issue.
