epan/dissectors/packet-wcp.c in the WCP dissector in Wireshark 1.10.x before 1.10.14 and 1.12.x before 1.12.5 improperly refers to previously processed bytes, which allows remote attackers to cause a denial of service (application crash) via a crafted packet, a different vulnerability than CVE-2015-2188.
CVE-2015-3811
This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 5.0 — v2 rates that MEDIUM (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:N/AC:L/Au:N/C:N/I:N/A:P. CVSS v2 is an older, coarser metric than v3.1/v4.0 (no Scope, no User Interaction, no Attack Requirements), so it is not directly comparable to a v3 or v4 score. NVD has never re-scored this record under v3. EPSS predicts 3.0% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.
