BASH PATCH REPORT
|
|
=================
|
|
|
|
Bash-Release: 3.2
|
|
Patch-ID: bash32-015
|

|
Bug-Description:
|
|
|
|
Under certain circumstances, when using FIFOs for process substitution,
|
|
bash fails to unlink the FIFOs. This leaves open file descriptors that
|
|
can cause the shell to hang and litters the file system.
|
|
|
|
