This bulletin contains two (2) F5 Networks security advisories. - --------------------------BEGIN INCLUDED TEXT-------------------- K09092524:Binutils vulnerability CVE-2019-9074 Security Advisory Original Publication Date: 24 May, 2019 Security Advisory Description An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an out-of-bounds read leading to a SEGV in bfd_getl32 in libbfd.c, when called from pex64_get_runtime_function in pei-x86_64.c. (CVE-2019-9074) Impact Successful exploitation of this vulnerability could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS). Security Advisory Status F5 Product Development has assigned ID 785209 (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 release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table. For more information about security advisory versioning, refer to K51812227: Understanding Security Advisory versioning. +-------------------+------+----------+----------+----------+------+----------+ | | |Versions |Fixes | |CVSSv3|Vulnerable| |Product |Branch|known to |introduced|Severity |score^|component | | | |be |in | |1 |or feature| | | |vulnerable| | | | | +-------------------+------+----------+----------+----------+------+----------+ | |15.x |15.0.0 |None | | | | | +------+----------+----------+ | | | |BIG-IP (LTM, AAM, |14.x |14.1.0 |None | | | | |AFM, Analytics, +------+----------+----------+ | | | |APM, ASM, DNS, Edge|13.x |None |Not | | | | |Gateway, FPS, GTM, | | |applicable|Medium |5.3 |Binutils | |Link Controller, +------+----------+----------+ | | | |PEM, |12.x |None |Not | | | | |WebAccelerator) | | |applicable| | | | | +------+----------+----------+ | | | | |11.x |None |Not | | | | | | | |applicable| | | | +-------------------+------+----------+----------+----------+------+----------+ |Enterprise Manager |3.x |None |Not |Not |None |None | | | | |applicable|vulnerable| | | +-------------------+------+----------+----------+----------+------+----------+ | |6.x |None |Not | | | | |BIG-IQ Centralized | | |applicable|Not | | | |Management +------+----------+----------+vulnerable|None |None | | |5.x |None |Not | | | | | | | |applicable| | | | +-------------------+------+----------+----------+----------+------+----------+ |F5 iWorkflow |2.x |None |Not |Not |None |None | | | | |applicable|vulnerable| | | +-------------------+------+----------+----------+----------+------+----------+ |Traffix SDC |5.x |None |Not |Not |None |None | | | | |applicable|vulnerable| | | +-------------------+------+----------+----------+----------+------+----------+ ^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. 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. Mitigation To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and restrict command line access for affected systems to trusted users.
