FreeBSD : zeek -- potential DoS vulnerability (fe7031d3-3000-4b43-9fa6-52c2b624b8f9)

high Nessus Plugin ID 208214

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 fe7031d3-3000-4b43-9fa6-52c2b624b8f9 advisory.

 Tim Wojtulewicz of Corelight reports:
 Adding to the POP3 hardening in 7.0.2, the parser now simply discards too many pending commands, rather than any attempting to process them. Further, invalid server responses do not result in command completion anymore.
 Processing out-of-order commands or finishing commands based on invalid server responses could result in inconsistent analyzer state, potentially triggering null pointer references for crafted traffic.

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.
