FreeBSD : Mozilla -- cookie shadowing (5abc2187-685e-11f0-a12d-b42e991fc52e)

critical Nessus Plugin ID 242927

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 5abc2187-685e-11f0-a12d-b42e991fc52e advisory.

[email protected] reports:
Setting a nameless cookie with an equals sign in the value shadowed other cookies. Even if the nameless cookie was set over HTTP and the shadowed cookie included the `Secure` attribute.

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.
