Title: Red Hat Linux Inetd Daytime Denial of Service Vulnerability

Severity: MODERATE

Description:

inetd is the process which provides standard Internet services such as echo, daytime, time, discard and chargen.

Version of inetd shipped with RedHat Linux 6.2 improperly handles the closing of sockets created in handling requests to inetd's daytime service. As a result, new connections to daytime cause affected versions of inetd to leak resources over time.

By issuing multiple daytime requests, a remote attacker could cause inetd to consume its available resources and crash.

Affected Products:

  • RedHat Linux 6.2.0
  • RedHat inetd-0.16-4.i386.rpm 0.0.0
