Synopsis
Ethereal is vulnerable to numerous vulnerabilities potentially resulting in
the execution of arbitrary code or abnormal termination.
2.
Impact Information
Background
Ethereal is a feature-rich network protocol analyzer.
Description
There are numerous vulnerabilities in versions of Ethereal prior
to 0.10.12, including:
- The SMB dissector could overflow a
buffer or exhaust memory (CAN-2005-2365).
- iDEFENSE discovered
that several dissectors are vulnerable to format string overflows
(CAN-2005-2367).
- Additionally multiple potential crashes in
many dissectors have been fixed, see References for further
details.
Impact
An attacker might be able to use these vulnerabilities to crash
Ethereal or execute arbitrary code with the permissions of the user
running Ethereal, which could be the root user.
3.
Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All Ethereal users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.12"
