Hi,

The following vulnerabilities were published for snort.

CVE-2023-20246[0]:
| Multiple Cisco products are affected by a vulnerability in Snort
| access control policies that could allow an unauthenticated, remote
| attacker to bypass the configured policies on an affected system.
| This vulnerability is due to a logic error that occurs when the
| access control policies are being populated. An attacker could
| exploit this vulnerability by establishing a connection to an
| affected device. A successful exploit could allow the attacker to
| bypass configured access control rules on the affected system.

CVE-2023-20031[1]:
| A vulnerability in the SSL/TLS certificate handling of Snort 3
| Detection Engine integration with Cisco Firepower Threat Defense
| (FTD) Software could allow an unauthenticated, remote attacker to
| cause the Snort 3 detection engine to restart. This vulnerability is
| due to a logic error that occurs when an SSL/TLS certificate that is
| under load is accessed when it is initiating an SSL connection.
| Under specific, time-based constraints, an attacker could exploit
| this vulnerability by sending a high rate of SSL/TLS connection
| requests to be inspected by the Snort 3 detection engine on an
| affected device. A successful exploit could allow the attacker to
| cause the Snort 3 detection engine to reload, resulting in either a
| bypass or a denial of service (DoS) condition, depending on device
| configuration. The Snort detection engine will restart
| automatically. No manual intervention is required.
