FreeBSD : Weechat -- Multiple vulnerabilities (0d5b4884-8c2b-11f1-8144-8447094a420f)

high Nessus Plugin ID 331319

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 0d5b4884-8c2b-11f1-8144-8447094a420f advisory.

 The Weechat project reports:
 Use-after-free and double free when a remote relay sends an event with an array as body.
 Use-after-free in the irc plugin when a batched message disconnects the server.
 Stack buffer overflow when building a JOIN command with channel keys.

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.
