CVE-2011-3483

Status: ModifiedMedium (4.3)—💥 Exploit

Wireshark 1.6.x before 1.6.2 allows remote attackers to cause a denial of service (application crash) via a malformed capture file that leads to an invalid root tvbuff, related to a "buffer exception handling vulnerability."

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
