Vulnerability from certfr_avis

Une vulnérabilité a été découverte dans Squid. Elle permet à un attaquant de provoquer un déni de service à distance.

Solution

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

Squid versions 5.x sans le correctif de sécurité SQUID-2023_11
Squid versions 6.x antérieures à 6.6 ou sans le correctif de sécurité SQUID-2023_11

L'éditeur indique que les versions antérieures à 5.0.5 sont supposées vulnérables et ne bénéficieront pas d'un correctif de sécurité.

Severity ?

6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

CWE

CWE-825 - Expired Pointer Dereference

Summary

Squid is a caching proxy for the Web. Due to an expired pointer reference bug, Squid prior to version 6.6 is vulnerable to a Denial of Service attack against Cache Manager error responses. This problem allows a trusted client to perform Denial of Service when generating error pages for Client Manager reports. Squid older than 5.0.5 have not been tested and should be assumed to be vulnerable. All Squid-5.x up to and including 5.9 are vulnerable. All Squid-6.x up to and including 6.5 are vulnerable. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. As a workaround, prevent access to Cache Manager using Squid's main access control: `http_access deny manager`.
