Last modified

CVE-2007-5277 is a vulnerability of currently unknown severity. Microsoft Internet Explorer 6 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, a different issue than CVE-2006-4560.. EPSS estimates a 9.71% chance of exploitation in the next 30 days.
