Debian: DSA-4932-1 Critical: Tor Denial Of Service Threats

Multiple security vulnerabilities were discovered in Tor, a
connection-based low-latency anonymous communication system, which
could result in denial of service or spoofing.

For the stable distribution (buster), these problems have been fixed in
version 0.3.5.15-1.

We recommend that you upgrade your tor packages.
