Debian Security Advisory

DLA-2254-1 alpine -- LTS security update

Date Reported:
25 Jun 2020
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 963179.
In Mitre's CVE dictionary: CVE-2020-14929.
More information:


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.
