Security Advisory Description
Heap-based buffer overflow in PCRE 8.34 through 8.37 and PCRE2 10.10 allows
remote attackers to execute arbitrary code via a crafted regular expression, as
demonstrated by /^(?P=B)((?P=B)(?J:(?P<B>c)(?P<B>a(?P=B)))>WGXCREDITS)/, a
different vulnerability than CVE-2015-8384. (CVE-2015-3210)
Impact
An locally authenticated attacker may be able to execute arbitrary code in the
context of the user running the affected application when the vulnerability is
exploited. However, affected F5 products that contain the vulnerable software
component do not use the components in a way which exposes this vulnerability.
Security Advisory Status
F5 Product Development has assigned ID 533930 (BIG-IQ and Enterprise Manager)
to this vulnerability, and has evaluated the currently supported releases for
potential vulnerability.
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

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 Versions known to be not vulnerable 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.
There are no remote access vectors for this issue, and there is no data plane
exposure. The context of an attacker is a locally authenticated user.
Mitigation
To mitigate this vulnerability for affected F5 products, you should only permit
management access to F5 products over a secure network and limit shell access
to trusted users. For more information, refer to K13309: Restricting access to
the Configuration utility by source IP address (11.x - 13.x) and K13092:
Overview of securing access to the BIG-IP system.
