CVE-2005-0739

Status: ModifiedMedium (5)—💥 Exploit

The IAPP dissector (packet-iapp.c) for Ethereal 0.9.1 to 0.10.9 does not properly use certain routines for formatting strings, which could leave it vulnerable to buffer overflows, as demonstrated using modified length values that are not properly handled by the dissect_pdus and pduval_to_str functions.

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.
