| Package | Affected versions | Patched versions |
|---|---|---|
| thunderbird | < 60.5.0 | 60.5.0 |
A crash can occur when processing a crafted S/MIME message or an XPI package containing a crafted signature. This can be used as a denial-of-service (DOS) attack because Thunderbird reopens the last seen message on restart, triggering the crash again. This vulnerability affects Thunderbird < 60.5.
