Synopsis

The remote Debian host is missing a security update.

Description

The update of squid3 released as DLA-2278-2 introduced a regression due to the updated fix for CVE-2019-12529. The new Kerberos authentication code prevented base64 token negotiation. Updated squid3 packages are now available to correct this issue.

For Debian 9 stretch, this problem has been fixed in version 3.5.23-5+deb9u4.

We recommend that you upgrade your squid3 packages.

For the detailed security status of squid3 please refer to its security tracker page at:

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 packages.
