| 			     BASH PATCH REPORT
 | |
| 			     =================
 | |
| 
 | |
| Bash-Release:	4.2
 | |
| Patch-ID:	bash42-033
 | |

 | |
| Bug-Reported-by:	David Leverton <levertond@googlemail.com>

| 
 | |
| Bug-Description:
 | |
| 
 | |
| Bash uses a static buffer when expanding the /dev/fd prefix for the test
 | |
| and conditional commands, among other uses, when it should use a dynamic
 | |
| buffer to avoid buffer overflow.
 | |
| 
 | |
| Patch (apply with `patch -p0'):
