| Package | Affected versions | Patched versions |
|---|---|---|
| botan | ≤ 1.11.21 |
botan 1.11.x before 1.11.22 improperly handles wildcard matching against hostnames, which might allow remote attackers to have unspecified impact via a valid X.509 certificate, as demonstrated by accepting *.example.com as a match for bar.foo.example.com.
