Several vulnerabilities were discovered in the HTTP/2 code of Apache Traffic Server, a reverse and forward proxy server, which could result in denial of service.

The fixes are too intrusive to backport to the version in the oldstable distribution (stretch). An upgrade to Debian stable (buster) is recommended instead.

For the stable distribution (buster), these problems have been fixed in version 8.0.2+ds-1+deb10u1.

We recommend that you upgrade your trafficserver packages.
