FreeBSD : Erlang/OTP -- TLS denial of service using invalid certificate chains (445d3f14-89e1-11f1-b35c-4c526214c986)

high Nessus Plugin ID 330270

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 445d3f14-89e1-11f1-b35c-4c526214c986 advisory.

 https://github.com/erlang/otp/security/advisories/GHSA-r5jr-mq46-vmhw reports:
 A TLS/DTLS peer can crash the remote node by sending a certificate chain containing two mutually cross-signed certificates in unordered form. When the receiving side attempts to build a valid chain path, it enters unbounded recursion between the two certificates (A issues B, B issues A) with no cycle detection or depth limit. The call stack and chain accumulator grow without bound until the process exhausts available memory and the BEAM node crashes.

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.
