3. Problem description:

Ethereal is a program for monitoring network traffic.

A number of security flaws have been discovered in Ethereal. On a system where Ethereal is running, a remote attacker could send malicious packets to trigger these flaws.

A flaw in the DICOM dissector could cause a crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1139 to this issue.

A invalid RTP timestamp could hang Ethereal and create a large temporary file, possibly filling available disk space. (CAN-2004-1140)

The HTTP dissector could access previously-freed memory, causing a crash. (CAN-2004-1141)

An improperly formatted SMB packet could make Ethereal hang, maximizing CPU utilization. (CAN-2004-1142)

The COPS dissector could go into an infinite loop. (CAN-2005-0006)

The DLSw dissector could cause an assertion, making Ethereal exit prematurely. (CAN-2005-0007)

The DNP dissector could cause memory corruption. (CAN-2005-0008)

The Gnutella dissector could cause an assertion, making Ethereal exit prematurely. (CAN-2005-0009)

The MMSE dissector could free static memory, causing a crash. (CAN-2005-0010)

The X11 protocol dissector is vulnerable to a string buffer overflow. (CAN-2005-0084)

Users of Ethereal should upgrade to these updated packages which contain version 0.10.9 that is not vulnerable to these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:
