Package : squid
Version : 2.7.STABLE9-4.1+deb7u3
CVE ID : CVE-2018-1000027
Debian Bug : 888720
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.
