1 | BASH PATCH REPORT |
| 2 | ================= | |
| 3 | ||
| 4 | Bash-Release: 5.2 | |
| 5 | Patch-ID: bash52-010 | |
| 6 | ||
| 7 | Bug-Reported-by: larsh@apache.org | |
| 8 | Bug-Reference-ID: | |
| 9 | Bug-Reference-URL: https://savannah.gnu.org/support/?110744 | |
| 10 | ||
| 11 | Bug-Description: | |
| 12 | ||
| 13 | Bash-5.2 checks the first 128 characters of an executable file that execve() | |
| 14 | refuses to execute to see whether it's a binary file before trying to | |
| 15 | execute it as a shell script. This defeats some previously-supported use | |
| 16 | cases like "self-executing" jar files or "self-uncompressing" scripts. | |
| 17 | ||
