Description Murray McAllister 2014-09-17 02:12:07 EDT

An infinite loop issue was discovered in Wireshark's MEGACO dissector. It may be possible to make Wireshark consume an excessive amount of CPU 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 1.12.0, and 1.10.0 to 1.10.9. It is fixed in versions 1.12.1 and 1.10.10.

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=10333

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