Package : squid3
Version : 3.5.23-5+deb9u3
Debian Bug : 965012
The update of squid3 released as DLA-2278-1 contained an incomplete
fix for CVE-2019-12523 that prevented services which rely on the icap
or ecap protocol to function properly. Updated squid3 packages are now
available to correct this issue.
In addition the patch for CVE-2019-12529 was improved to use more code
from Debian's cryptographic nettle library.
For Debian 9 stretch, this problem has been fixed in version
3.5.23-5+deb9u3.
We recommend that you upgrade your squid3 packages.

Debian Bug : 950802 931478 950925 912294
It was found that Squid, a high-performance proxy caching server for
web clients, has been affected by multiple security vulnerabilities.
Due to incorrect input validation and URL request handling it was
possible to bypass access restrictions for restricted HTTP servers
and to cause a denial-of-service.
For Debian 9 stretch, these problems have been fixed in version
3.5.23-5+deb9u2.
We recommend that you upgrade your squid3 packages.
