Title: Ethereal: Multiple vulnerabilities in protocol dissectors (GLSA 200604-17)
Severity: high
Exploitable: remote
Date: April 27, 2006
Bug(s): #130505
ID: 200604-17

Synopsis

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

Background

Ethereal is a feature-rich network protocol analyzer.

Affected Packages

Package: net-analyzer/ethereal
Vulnerable: < 0.99.0
Unaffected: >= 0.99.0
Architectures: All supported architectures


Description

Coverity discovered numerous vulnerabilities in versions of Ethereal prior to 0.99.0, including:
  • buffer overflows in the ALCAP (CVE-2006-1934), COPS (CVE-2006-1935) and telnet (CVE-2006-1936) dissectors.
  • buffer overflows in the NetXray/Windows Sniffer and Network Instruments file code (CVE-2006-1934).
For further details please consult the references below.

Impact

An attacker might be able to exploit 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.99.0"
