http://security.gentoo.org/

Severity:	high
Title:	Ethereal: Multiple vulnerabilities in protocol dissectors
Date:	10/30/2005
Bugs:	#109348
ID:	200510-25

Synopsis

Ethereal is vulnerable to numerous vulnerabilities, potentially resulting in the execution of arbitrary code or abnormal termination.

Background

Ethereal is a feature-rich network protocol analyzer.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/ethereal	< 0.10.13-r1	>= 0.10.13-r1	All supported architectures

Description

There are numerous vulnerabilities in versions of Ethereal prior to 0.10.13, including:

The SLIM3 and AgentX dissectors could overflow a buffer (CVE-2005-3243).
iDEFENSE discovered a buffer overflow in the SRVLOC dissector (CVE-2005-3184).
Multiple potential crashes in many dissectors have been fixed, see References for further details.

Furthermore an infinite loop was discovered in the IRC protocol dissector of the 0.10.13 release (CVE-2005-3313).

Impact

An attacker might be able to use these vulnerabilities to crash Ethereal or execute arbitrary code with the permissions of the user running Ethereal, which could be the root user.

Workaround

There is no known workaround at this time.

Resolution

All Ethereal users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.13-r1"
