All supported architectures
Multiple vulnerabilities exist in Ethereal, which may allow an attacker to
run arbitrary code or crash the program.
Ethereal is a feature rich network protocol analyzer.
There are multiple vulnerabilities in versions of Ethereal earlier than
- 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
- Various vulnerabilities in JXTA and sFlow dissectors.
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.
For a temporary workaround you can disable all affected protocol
dissectors. However, it is strongly recommended that you upgrade to the
latest stable version.
All Ethereal users should upgrade to the latest version:
