Debian DLA-1267-1 : squid security update

high Nessus Plugin ID 106590

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Squid, a high-performance proxy caching server for web clients, has been found vulnerable to denial of service attacks associated with ESI response processing and intermediate CA certificate downloading.

CVE-2018-1000027

Incorrect pointer handling resulted in the possibility of a remote client delivering certain HTTP requests in conjunction with certain trusted server reponses involving the processing of ESI responses or downloading of intermediate CA certificates to trigger a denial of service for all clients accessing the squid service.

For Debian 7 'Wheezy', these problems have been fixed in version 2.7.STABLE9-4.1+deb7u3.

We recommend that you upgrade your squid packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected squid, and squid-common packages.
