Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

.
ryu is a Component-based Software-defined Networking Framework
Affected versions of this package are vulnerable to Infinite Loop due to the improper handling of OFPGroupDescStats
in *parser.py
. An attacker can trigger an infinite loop by setting OFPBucket.len
to 0.
