Ethereal: Multiple vulnerabilities in protocol dissectors

Ethereal: Multiple vulnerabilities in protocol dissectors Ethereal is vulnerable to numerous vulnerabilities, potentially resulting in the execution of arbitrary code. Ethereal 2006-04-27 2006-04-27 130505 remote 0.99.0 0.99.0

Ethereal is a feature-rich network protocol analyzer.

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.

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.

There is no known workaround at this time.

All Ethereal users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.99.0"
