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

high Nessus Plugin ID 128621
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
