Severity: high
Exploitable: remote
Date: March 12, 2005

Bug(s): #84547
ID: 200503-16

Synopsis


Multiple vulnerabilities exist in Ethereal, which may allow an attacker to
run arbitrary code or crash the program.


Background


Ethereal is a feature rich network protocol analyzer.


Affected Packages

Package: net-analyzer/ethereal
Vulnerable: < 0.10.10
Unaffected: >= 0.10.10
Architectures: All supported architectures


Description


There are multiple vulnerabilities in versions of Ethereal earlier than
0.10.10, including:

• The Etheric, 3GPP2 A11 and IAPP dissectors are vulnerable to buffer
  overflows (CAN-2005-0704, CAN-2005-0699 and CAN-2005-0739).
• The GPRS-LLC could crash when the "ignore cipher bit" option is
  enabled (CAN-2005-0705).
• Various vulnerabilities in JXTA and sFlow dissectors.

Impact


An attacker might be able to use these vulnerabilities to crash
Ethereal and 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. However, it is strongly recommended that you upgrade to the
latest stable version.


Resolution


All Ethereal users should upgrade to the latest version:
