All supported architectures
Mulitple overflows and vulnerabilities exist in Ethereal which may allow an
attacker to crash the program or run arbitrary code.
Quote from http://www.ethereal.com
"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:
