Details

Description

The WSP dissector could go into an infinite loop. Discovered by Chris Benedict, Aurelien Delaitre, NIST SAMATE Project.

Impact

It may be possible to make Wireshark consume excessive CPU resources by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

Resolution

Upgrade to Wireshark 2.0.5, 1.12.13 or later.
