Ethereal: Multiple vulnerabilities — GLSA 200507-27

Ethereal is vulnerable to numerous vulnerabilities potentially resulting in the execution of arbitrary code or abnormal termination.

Affected Packages

net-analyzer/ethereal on all architectures
Affected versions < 0.10.12
Unaffected versions >= 0.10.12

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.

Workaround

There is no known workaround at this time.

Resolution

All Ethereal users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.12"
