Debian DLA-2254-1 : alpine security update

high Nessus Plugin ID 137841

Language:

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2020-14929

Alpine before 2.23 silently proceeds to use an insecure connection after a /tls is sent in certain circumstances involving PREAUTH, which is a less secure behavior than the alternative of closing the connection and letting the user decide what they would like to do.

For Debian 8 'Jessie', this problem has been fixed in version 2.11+dfsg1-3+deb8u1.

We recommend that you upgrade your alpine packages.

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.
