Debian DSA-5258-1 : squid - security update

high Nessus Plugin ID 166277

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5258 advisory.

- Mikhail Evdokimov (aka konata) reports: Due to inconsistent handling of internal URIs Squid is vulnerable to Exposure of Sensitive Information about clients using the proxy.
This problem allows a trusted client to directly access cache manager information bypassing the manager ACL protection. The available cache manager information contains records of internal network structure, client credentials, client identity and client traffic behaviour. (CVE-2022-41317)

- squid: buffer-over-read in SSPI and SMB authentication (CVE-2022-41318)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the squid packages.

For the stable distribution (bullseye), these problems have been fixed in version 4.13-10+deb11u2.
