Multiple vulnerabilities have been discovered in Ethereal, which can be exploited by malicious people to compromise a vulnerable system or cause a DoS (Denial-of-Service).

1) Stefan Esser has discovered thirteen boundary errors in the NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and TCAP protocol dissectors, which can be exploited to cause buffer overflows. This may allow execution of arbitrary code on a vulnerable system running Ethereal by sending a malicious packet or by tricking a user into opening a malicious packet trace file.

2) Ethereal can reportedly be crashed via a zero-length Presentation protocol selector.

3) Jonathan Heussser has discovered an error within the handling of RADIUS packets, which can cause Ethereal to crash.

4) An unspecified error within the handling of malformed colour filter files can reportedly cause a segmentation fault.

The vulnerabilities affect versions 0.8.13 through 0.10.2.

Solution
Update to version 0.10.3, when it becomes available.
