high Nessus Plugin ID 320569

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the d87db2a1-64d4-11f1-ab11-4c526214c986 advisory.

 https://github.com/erlang/otp/security/advisories/GHSA-6f4f-chj5-5g97 reports:
 A buffer overflow error when parsing SCTP ERROR or ABORT chunks has been fixed. This could lead to stack corruption and VM crash, but ultimately with hard work by an attacker be refined into maybe even remote code execution.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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.
