| GNU Bash through 4.3 processes trailing strings after function
definitions in the values of environment variables, which allows
remote attackers to execute arbitrary code via a crafted environment,
as demonstrated by vectors involving the ForceCommand feature in
OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP
Server, scripts executed by unspecified DHCP clients, and other
situations in which setting the environment occurs across a privilege
boundary from Bash execution, aka "ShellShock." NOTE: the original
fix for this issue was incorrect; CVE-2014-7169 has been assigned to
cover the vulnerability that is still present after the incorrect fix.
