Mulitple overflows and vulnerabilities exist in Ethereal which may allow an attacker to crash the program or run arbitrary code.

Affected packages

net-analyzer/ethereal on all architectures
Affected versions <= 0.10.2
Unaffected versions >= 0.10.3


Quote from

"Ethereal is used by network professionals around the world for troubleshooting, analysis, software and protocol development, and education. It has all of the standard features you would expect in a protocol analyzer, and several features not seen in any other product. Its open source license allows talented experts in the networking community to add enhancements. It runs on all popular computing platforms, including Unix, Linux, and Windows."


There are multiple vulnerabilities in versions of Ethereal earlier than 0.10.3, including:

  • Thirteen buffer overflows in the following protocol dissectors: NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and TCAP.
  • A zero-length Presentation protocol selector could make Ethereal crash.
  • A vulnerability in the RADIUS packet dissector which may crash ethereal.
  • A corrupt color filter file could cause a segmentation fault.


These vulnerabilities may cause Ethereal to crash or may allow an attacker to run arbitrary code on the user's computer.


While a workaround is not currently known for this issue, all users are advised to upgrade to the latest version of the affected package.


All users should upgrade to the current version of the affected package:

 # emerge sync
 # emerge -pv ">=net-analyzer/ethereal-0.10.3"
 # emerge ">=net-analyzer/ethereal-0.10.3"
