- Source-reported fixed versions
- No fixed-version detail extracted. This does not mean no fix exists.
- Mitigation guidance
- No practical runtime mitigation is available in the shipped build. Do not pass untrusted data into dash printf/echo %b or into dash -c as a positional argument. The fix is to raise the CHECKSTRSPACE reservation at both printf call sites to 8. The later unaligned-access memcpy change in conv_escape does not enlarge that reservation and does not fix this issue.
