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 0.10.13, including:
- The SLIM3 and AgentX dissectors
could overflow a buffer (CVE-2005-3243).
- iDEFENSE discovered a
buffer overflow in the SRVLOC dissector (CVE-2005-3184).
- Multiple potential crashes in many dissectors have been fixed, see
References for further details.
Furthermore an infinite
loop was discovered in the IRC protocol dissector of the 0.10.13
release (CVE-2005-3313).
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-0.10.13-r1"
