1 | BASH PATCH REPORT |
| 2 | ================= | |
| 3 | ||
| 4 | Bash-Release: 4.3 | |
| 5 | Patch-ID: bash43-009 | |
| 6 | ||
| 7 | Bug-Reported-by: Matthias Klose <doko@debian.org> | |
| 8 | Bug-Reference-ID: <53346FC8.6090005@debian.org> | |
| 9 | Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2014-03/msg00171.html | |

| 11 | Bug-Description: | |
| 12 | ||
| 13 | There is a problem with unsigned sign extension when attempting to reallocate | |
| 14 | the input line when it is fewer than 3 characters long and there has been a | |
| 15 | history expansion. The sign extension causes the shell to not reallocate the | |
| 16 | line, which results in a segmentation fault when it writes past the end. | |
| 17 | ||
