Vulnerability from fkie_nvd - Published: 2007-10-08 23:17 - Updated: 2026-04-23 00:35
Severity
Summary
Opera 9 drops DNS pins based on failed connections to irrelevant TCP ports, which makes it easier for remote attackers to conduct DNS rebinding attacks, as demonstrated by a port 81 URL in an IMG SRC, when the DNS pin had been established for a session on port 80.
