BASH PATCH REPORT
=================
Bash-Release: 2.05b
Patch-ID: bash205b-012
Bug-Reported-by: Michal Zalewski <lcamtuf@coredump.cx>
Bug-Reference-ID:
Bug-Reference-URL:
Bug-Description:
When bash is parsing a function definition that contains a here-document
delimited by end-of-file (or end-of-string), it leaves the closing delimiter
uninitialized. This can result in an invalid memory access when the parsed
function is later copied.
Patch:
