- Security database references:
- In the Debian bugtracking system: Bug 888720.
In Mitre's CVE dictionary: CVE-2018-1000027.
- More information:
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.
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.
