Package : snort
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 the stable distribution (bullseye), these problems have been fixed in
version 2.9.20-0+deb11u1.
We recommend that you upgrade your snort packages.
For the detailed security status of snort please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/snort
Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
