CVE-2005-0356 EXPLOIT
5.0
MEDIUM · CVSS 2.0 · EPSS 82.8% (pctl 100)
Patch early
A public exploit exists.
Description
Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.
