Debian DLA-2455-1 : packer security update

high Nessus Plugin ID 143109
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security update.


golang-go.crypto was recently updated with a fix for CVE-2020-9283.
This in turn requires all packages that use the affected code to be recompiled in order to pick up the security fix.


SSH signature verification could cause Panic when given invalid Public key.

For Debian 9 stretch, this problem has been fixed in version 0.10.2+dfsg-6+deb9u1.

We recommend that you upgrade your packer packages.

For the detailed security status of packer 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.
