Debian DSA-4772-1 : httpcomponents-client - security update

medium Nessus Plugin ID 141464
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.


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


Priyank Nigam discovered that HttpComponents Client, a Java HTTP agent implementation, could misinterpret malformed authority component in a request URI and pick the wrong target host for request execution.


Upgrade the httpcomponents-client packages.

For the stable distribution (buster), this problem has been fixed in version 4.5.7-1+deb10u1.
