Debian DSA-4520-1 : trafficserver - security update (Empty Frames Flood) (Ping Flood) (Reset Flood) (Settings Flood)

high Nessus Plugin ID 128621

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the trafficserver packages.

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