Severity: normal

Usertags: pu
The attached debdiff for leptonlib fixes five CVEs in Buster:
- CVE-2020-36277
- CVE-2020-36278
- CVE-2020-36279
- CVE-2020-36280
- CVE-2020-36281
According to Moritz, they should have been marked as no-dsa by the
security team.
The fix has been uploaded to Jessie long time ago and nobody complained up
to now. It already made it to unstable and will soon migrate to testing.
So Buster is the only release that is missing the patches.
