FreeBSD : OpenSSL -- OOB memory access vulnerability (c6f4177c-8e29-11ef-98e7-84a93843eb75)

medium Nessus Plugin ID 209340

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 c6f4177c-8e29-11ef-98e7-84a93843eb75 advisory.

The OpenSSL project reports:
Low-level invalid GF(2^m) parameters lead to OOB memory access (CVE-2024-9143) (Low) Use of the low-level GF(2^m) elliptic curve APIs with untrusted explicit values for the field polynomial can lead to out-of-bounds memory reads or writes.

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.
