bash: parser can allow out-of-bounds memory access while handling redir_stack

It was identified that the fixed-sized redirstack could be forced to overflow in the Bash parser, resulting in memory corruption, and possibly leading to arbitrary code execution when evaluating untrusted input that would not otherwise be run as code...

bash: code execution via specially-crafted environment (Incomplete fix for CVE-2014-6271)

It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. An attacker could potentially use this flaw to override or bypass environment restrictions to execute shell...
