Gentoo Linux Security Advisory
Title: Ethereal: Multiple vulnerabilities (GLSA 200501-27)
Severity: high
Exploitable: remote
Date: January 20, 2005
Bug(s): #78559
ID: 200501-27
Synopsis
Multiple vulnerabilities exist in Ethereal, which may allow an attacker to run arbitrary code, crash the program or perform DoS by CPU and disk utilization.
Background
Ethereal is a feature rich network protocol analyzer.
Affected Packages
Package: net-analyzer/ethereal
Vulnerable: < 0.10.9
Unaffected: >= 0.10.9
Architectures: All supported architectures
Description
There are multiple vulnerabilities in versions of Ethereal earlier than 0.10.9, including: - 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 statically-allocated memory (CAN-2005-0010).
- The X11 dissector is vulnerable to a string buffer overflow (CAN-2005-0084).
Impact
An attacker might be able to use these vulnerabilities to crash Ethereal, perform DoS by CPU and disk space utilization or even execute arbitrary code with the permissions of the user running Ethereal, which could be the root user.
Workaround
For a temporary workaround you can disable all affected protocol dissectors by selecting Analyze->Enabled Protocols... and deselecting them from the list. However, it is strongly recommended to upgrade to the latest stable version.
Resolution
All Ethereal users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.9" |
