Description Murray McAllister 2014-11-13 04:29:51 UTC

It was reported that Wireshark's SigComp dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

This is reported to affect Wireshark versions 1.10.0 to 1.10.10. It is fixed in versions 1.12.2 and 1.10.11.

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=10662

The version of Wireshark in Red Hat Enterprise Linux 5 and 6 is older than 1.10.x, and may not be affected. The version of Wireshark in Red Hat Enterprise Linux 7 is affected.
