Package : salt
CVE ID : CVE-2020-11651 CVE-2020-11652
Debian Bug : 959684

The update for salt for the oldstable distribution (stretch) released as
DSA 4676-1 contained an incomplete fix to address CVE-2020-11651 and
CVE-2020-11652. Updated salt packages are now available to correct this
issue. For reference, the original advisory text follows.

Several vulnerabilities were discovered in salt, a powerful remote
execution manager, which could result in retrieve of user tokens from
the salt master, execution of arbitrary commands on salt minions,
arbitrary directory access to authenticated users or arbitrary code
execution on salt-api hosts.

For the oldstable distribution (stretch), these problems have been fixed
in version 2016.11.2+ds-1+deb9u4.

We recommend that you upgrade your salt packages.
