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-2018-1000024
Incorrect pointer handling resulted in the ability of a remote server to return a crafted ESI response which could trigger a denial of service for all clients accessing the Squid service. This issue affects the Squid custom ESI parser.
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 3.1.20-2.2+deb7u8.
We recommend that you upgrade your squid3 packages.
