Ethereal: Multiple vulnerabilities
Gentoo Linux Security Advisory
||GLSA 200507-27 / Ethereal
||July 28, 2005
||July 28, 2005: 01
All supported architectures
Ethereal is vulnerable to numerous vulnerabilities potentially resulting in
the execution of arbitrary code or abnormal termination.
Ethereal is a feature-rich network protocol analyzer.
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
- Additionally multiple potential crashes in
many dissectors have been fixed, see References for further
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.
There is no known workaround at this time.
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"
