1 | BASH PATCH REPORT |
| 2 | ================= | |
| 3 | ||
| 4 | Bash-Release: 4.3 | |
| 5 | Patch-ID: bash43-029 | |
| 6 | ||
| 7 | Bug-Reported-by: Michal Zalewski <lcamtuf@coredump.cx> | |
| 8 | Bug-Reference-ID: | |

| 11 | Bug-Description: | |
| 12 | ||
| 13 | When bash is parsing a function definition that contains a here-document | |
| 14 | delimited by end-of-file (or end-of-string), it leaves the closing delimiter | |
| 15 | uninitialized. This can result in an invalid memory access when the parsed | |
| 16 | function is later copied. | |
| 17 | ||
| 18 | Patch (apply with `patch -p0'): | |
