Synopsis

ethereal security update

Type/Severity

Security Advisory: Moderate

Topic

Updated Ethereal packages that fix various security vulnerabilities are now
available.

Description

Ethereal is a program for monitoring network traffic.

The SNMP dissector in Ethereal releases 0.8.15 through 0.10.4 contained a
memory read flaw. On a system where Ethereal is running, a remote
attacker could send malicious packets that could cause Ethereal to crash or
possibly execute arbitrary code. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-0635 to this issue.

The SMB dissector in Ethereal releases 0.9.15 through 0.10.4 contained a
null pointer flaw. On a system where Ethereal is running, a remote
attacker could send malicious packets that could cause Ethereal to crash.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0634 to this issue.

The iSNS dissector in Ethereal releases 0.10.3 through 0.10.4 contained an
integer overflow flaw. On a system where Ethereal is running, a remote
attacker could send malicious packets that could cause Ethereal to crash or
possibly execute arbitrary code. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-0633 to this issue.

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