| Author | Note |
|---|---|
| mdeslaur | reproducer causes an out-of-bounds read, so DoS exact upstream fix has not been identified as of 2021-09-17 |
| ccdm94 | the fix for this issue was most likely released before the vulnerability was discovered, so version 4.1.0 of tiff is already unaffected. According to http://bugzilla.maptools.org/ show_bug.cgi?id=2848, the fix could be the one in commit 1fb9e731ef3. This is also in the Debian page for this CVE. |
