"The following CVEs were reported against yubikey-val.

CVE-2020-10184

The verify endpoint in YubiKey Validation Server before 2.40 does not
check the length of SQL queries, which allows remote attackers to
cause a denial of service, aka SQL injection.

CVE-2020-10185

The sync endpoint in YubiKey Validation Server before 2.40 allows
remote attackers to replay an OTP.

For Debian 8 'Jessie', these problems have been fixed in version
2.27-1+deb8u1.

We recommend that you upgrade your yubikey-val packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
