Azure Linux 3.0 Security Update: golang / python-tensorboard (CVE-2021-29923)

high Nessus Plugin ID 215307

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of golang / python-tensorboard installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2021-29923 advisory.

- Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR. (CVE-2021-29923)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
