CVE-2016-6513

Status: ModifiedMedium (5.9)—

epan/dissectors/packet-wbxml.c in the WBXML dissector in Wireshark 2.x before 2.0.5 does not restrict the recursion depth, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
