FreeBSD : zeek -- potential DoS vulnerabilty (a00c76d9-0c05-4d99-bef7-ae4521cb2a4d)

high Nessus Plugin ID 160061

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 a00c76d9-0c05-4d99-bef7-ae4521cb2a4d advisory.

 - Tim Wojtulewicz of Corelight reports: Fix potential unbounded state growth in the FTP analyzer when receiving a specially-crafted stream of commands. This may lead to a buffer overflow and cause Zeek to crash. Due to the possibility of this happening with packets received from the network, this is a potential DoS vulnerability. (a00c76d9-0c05-4d99-bef7-ae4521cb2a4d)

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.
