Details

Description

Multiple dissectors and other modules could leak memory. The TN3270, ISUP, LAPD, SMB2, GIOP, ASN.1, MIME multipart, H.223, and PCP dissectors were affected along with Wireshark and TShark. Discovered by Otto Airamo and Antti Levomäki, Forcepoint.

Impact

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.

Resolution

Upgrade to Wireshark 2.4.6, 2.2.14 or later.
