The remote Ubuntu 22.04 LTS / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6986-1 advisory.
David Benjamin discovered that OpenSSL incorrectly handled certain X.509 certificates. An attacker could possible use this issue to cause a denial of service or expose sensitive information.
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
