Security Advisory Description

Constructed ASN.1 types with a recursive definition (such as can be found in
PKCS7) could eventually exceed the stack given malicious input with excessive
recursion. This could result in a Denial Of Service attack. There are no such
structures used within SSL/TLS that come from untrusted sources so this is
considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in
OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n). (CVE-2018-0739)

Impact

BIG-IP / BIG-IQ / F5 iWorkflow / Enterprise Manager / Traffix SDC

When a carefully crafted malicious ASN.1 structure is loaded by an
authenticated administrative user using the OpenSSL command line utility, the
command line utility may stop responding. This vulnerability does not affect
X.509 certificates, SSL profiles, or SSL/TLS connections.

ARX / LineRate

There is no impact; F5 products are not affected by this vulnerability.

Security Advisory Status

F5 Product Development has assigned ID 713806, 713829, 713821, 713838 (BIG-IP),
ID 713971 (BIG-IQ/F5 iWorkflow), ID 713969 (Enterprise Manager), and CPF-24850,
CPF-24851, CPF-24852 (Traffix) to this vulnerability.

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 avoid processing untrusted PKCS
files on the affected systems.
