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.
|
||
|
|
|
||
|
