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.

Start learningThere is no fixed version for pyOpenSSL
.
Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') due to the session cache entering an incorrect state and failing to flush properly as it fills, leading to uncontrolled memory consumption. This condition is triggered under certain server configurations when processing TLSv1.3 sessions. Specifically, this occurs if the non-default SSL_OP_NO_TICKET
option is enabled, but not if early_data support is configured along with the default anti-replay protection. A malicious client could deliberately create this scenario to force a service disruption. It may also occur accidentally in normal operation.
Note:
This issue is only exploitable if the server supports TLSv1.3 and is configured with the SSL_OP_NO_TICKET
option enabled.
