CVE-2015-3813: Wireshark

Medium severity, CVSS 5.0. EPSS: 2.8% chance of exploitation in the next 30 days.

The fragment_add_work function in epan/reassemble.c in the packet-reassembly feature in Wireshark 1.12.x before 1.12.5 does not properly determine the defragmentation state in a case of an insufficient snapshot length, which allows remote attackers to cause a denial of service (memory consumption) via a crafted packet.

Affected products

• Wireshark Wireshark: version 1.12.0 only; version 1.12.1 only; version 1.12.2 only; version 1.12.3 only; version 1.12.4 only
