| BASH PATCH REPORT |
| ================= |
| |
| Bash-Release: 4.3 |
| Patch-ID: bash43-036 |
| |
| Bug-Reported-by: emanuelczirai@cryptolab.net |
| Bug-Reference-ID: <f962e4f556da5ebfadaf7afe9c78a8cb@cryptolab.net> |
| Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2015-02/msg00071.html |
| |
| Bug-Description: |
| |
| When evaluating and setting integer variables, and the assignment fails to |
| create a variable (for example, when performing an operation on an array |
| variable with an invalid subscript), bash attempts to dereference a null |
| pointer, causing a segmentation violation. |
| |
| Patch (apply with `patch -p0'): |
