CVE-2012-6054: Wireshark

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

The dissect_sflow_245_address_type function in epan/dissectors/packet-sflow.c in the sFlow dissector in Wireshark 1.8.x before 1.8.4 does not properly handle length calculations for an invalid IP address type, which allows remote attackers to cause a denial of service (infinite loop) via a packet that is neither IPv4 nor IPv6.

Affected products

• Wireshark Wireshark: version 1.8.0 only; version 1.8.1 only; version 1.8.2 only; version 1.8.3 only
