FreeBSD : Mozilla -- nullptr dereference (4d03efe7-685e-11f0-a12d-b42e991fc52e)

medium Nessus Plugin ID 242917

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 4d03efe7-685e-11f0-a12d-b42e991fc52e advisory.

 [email protected] reports:
 The JavaScript engine did not handle closed generators correctly and it was possible to resume them leading to a nullptr deref.

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.
