Bash: Code Injection

Bash: Code Injection A parsing flaw related to functions and environments in Bash could allow attackers to inject code. bash 2014-09-24 2014-10-04 523592 local, remote 3.1_p18 3.2_p52 4.0_p39 4.1_p12 4.2_p48 4.2_p48

Bash is the standard GNU Bourne Again SHell.

Stephane Chazelas reported that Bash incorrectly handles function definitions, allowing attackers to inject arbitrary code.

A remote attacker could exploit this vulnerability to execute arbitrary commands even in restricted environments.

There is no known workaround at this time.
