CVE-2018-9261: Debian Linux

High severity, CVSS 7.5. EPSS: 2.8% chance of exploitation in the next 30 days.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the NBAP dissector could crash with a large loop that ends with a heap-based buffer overflow. This was addressed in epan/dissectors/packet-nbap.c by prohibiting the self-linking of DCH-IDs.

Affected products

• Debian Debian Linux: version 7.0 only; version 8.0 only; version 9.0 only
• Wireshark Wireshark: from 2.2.0, up to and including 2.2.13; from 2.4.0, up to and including 2.4.5
