Description

The DTLS dissector in Wireshark 1.6.x before 1.6.14 and 1.8.x before 1.8.6 does not validate the fragment offset before invoking the reassembly state machine, which allows remote attackers to cause a denial of service (application crash) via a large offset value that triggers write access to an invalid memory location.

Affected products

Debian Linux: 7.0
Opensuse: 11.4, 12.1, 12.2, 12.3
Wireshark Foundation Wireshark: 1.8.0, 1.8.1, 1.8.2, 1.8.3, 1.8.4, 1.8.5 (+14)
