FreeBSD : zeek -- potential DoS vulnerability (8173e68a-88f3-4862-882c-6e58779d98e7)

high Nessus Plugin ID 297207

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 8173e68a-88f3-4862-882c-6e58779d98e7 advisory.

 Tim Wojtulewicz of Corelight reports:
 Zeek's HTTP analyzer can be tricked into interpreting Transfer-Encoding or Content-Length headers set in MIME entities within HTTP bodies and change the analyzer behavior.

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.
