critical Nessus Plugin ID 145319

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities were discovered in salt, a powerful remote execution manager. The flaws could result in authentication bypass and invocation of Salt SSH, creation of certificates with weak file permissions via the TLS execution module or shell injections with the Salt API using the SSH client.

Solution

Upgrade the salt packages.

For the stable distribution (buster), these problems have been fixed in version 2018.3.4+dfsg1-6+deb10u2.
