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 716d25a6-0fdc-11f1-bfdf-ff9355aecb00 advisory.

 Cary Phillips reports:
 [openexr] v3.4.5 [...] fixes an incorrect size check in istream_nonparallel_read that could lead to a buffer overflow on invalid input data.

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.
