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.

For the detailed security status of trafficserver please refer to its security tracker page at: [link moved to references]");
