K35040315 : glibc vulnerability CVE-2016-10739

Security Advisory Description

In the GNU C Library (aka glibc or libc6) through 2.28, the getaddrinfo function would successfully parse a string that contained an IPv4 address followed by whitespace and arbitrary characters, which could lead applications to incorrectly assume that it had parsed a valid string, without the possibility of embedded HTTP headers or other potentially dangerous substrings. (CVE-2016-10739)

Impact

BIG-IP and Traffix SDC

An attacker can exploit this vulnerability with other vulnerabilities that allow HTTP header injection and redirect HTTP connections to a malicious server.

For the BIG-IP system, there is no data plane and management plane exposure for this vulnerability; this is true for the Configuration utility and system processes that listen on the management port. However, command line utilities may be impacted. If you use any command line utilities that include the host name as an input, you should ensure that the input is properly sanitized.

BIG-IQ, Enterprise Manager, and F5 iWorkflow

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