QID 376568

A heap-based buffer overflow exists in GNU Bash before 4.3 when wide characters, not supported by the current locale set in the LC_CTYPE environment variable, are printed through the echo built-in function. A local attacker, who can provide data to print through the "echo -e" built-in function, may use this flaw to crash a script or execute code with the privileges of the bash process. This occurs because ansicstr() in lib/sh/strtrans.c mishandles u32cconv(). (CVE-2012-6711)

Vulnerable Component: BIG-IP ASM,LTM,APM

Affected Versions:
16.0.0 - 16.1.2
15.0.0 - 15.1.5
14.1.0 - 14.1.4

QID Detection Logic(Authenticated):
This QID checks for the vulnerable versions of F5 BIG-IP devices using the tmsh command.

Note: Detection has been kept potential as this vulnerability affects Bash before 4.3 only.

A local attacker can perform a buffer-overflow attack, which can lead to data corruption, allow the malicious code to be run, or cause the program to terminate.
