Debian DSA-4507-1 : squid - security update

critical Nessus Plugin ID 128125

Language:

Synopsis

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

Description

Several vulnerabilities were discovered in Squid, a fully featured web proxy cache. The flaws in the HTTP Digest Authentication processing, the HTTP Basic Authentication processing and in the cachemgr.cgi allowed remote attackers to perform denial of service and cross-site scripting attacks, and potentially the execution of arbitrary code.

Solution

Upgrade the squid packages.

For the stable distribution (buster), these problems have been fixed in version 4.6-1+deb10u1.
