Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.

Security Advisory Description

When a virtual server uses the inflate functionality to process a gzip bomb as
a payload, the BIG-IP system will experience a fatal error and may cause the
Traffic Management Microkernel (TMM) to produce a core file. (CVE-2018-15330)

Impact

An attacker may be able to disrupt traffic or cause the BIG-IP system to fail
over to another device in the device group. This issue is exposed only on the
BIG-IP system's data plane; there is no control plane exposure for this issue.

Security Advisory Status

F5 Product Development has assigned ID 727044 (BIG-IP) to this vulnerability.

To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your

^1The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.

^2The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.

Security Advisory Description

The dcdb_convert utility used by BIG-IP AAM fails to drop group permissions
when executing helper scripts, which could be used to leverage attacks against
the BIG-IP system. (CVE-2018-15331)

Impact

This issue does not have a direct exploit, but may be used to leverage attacks
against the BIG-IP system by way of the AAM module.

The dcdb_convert binary is typically run manually to update the capabilities
database. The risk of exploitation is from downloading a malformed capabilities
database, which includes an exploit and running it through the dcdb_convert
utility.
