When handling the filename directive in the Content-Disposition header, the
filename would be truncated if the filename contained a NULL character.
This could have led to reflected file download attacks potentially tricking
users to install malware. This vulnerability affects Firefox < 112, Focus
for Android < 112, Firefox ESR < 102.10, Firefox for Android < 112, and
Thunderbird < 102.10.
