Package        : alpine
Version        : 2.11+dfsg1-3+deb8u1
CVE ID         : CVE-2020-14929
Debian Bug     : 963179


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.
