BASH PATCH REPORT
|
|
=================
|
|
|
|
Bash-Release: 4.3
|
|
Patch-ID: bash43-029
|
|
|
|
Bug-Reported-by: Michal Zalewski <lcamtuf@coredump.cx>

|
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.
