Package : snort Version : 2.9.20-0+deb10u1 CVE ID : CVE-2020-3299 CVE-2020-3315 CVE-2021-1223 CVE-2021-1224 CVE-2021-1236 CVE-2021-1494 CVE-2021-1495 CVE-2021-34749 CVE-2021-40114 Debian Bug : 1021276

Multiple security vulnerabilities were discovered in snort, a flexible Network Intrusion Detection System, which could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or bypass filtering technology on an affected device and ex-filtrate data from a compromised host.

For Debian 10 buster, these problems have been fixed in version 2.9.20-0+deb10u1.

We recommend that you upgrade your snort packages.
