Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5845-1 advisory.

 David Benjamin discovered that OpenSSL incorrectly handled X.400 address processing. A remote attacker could possibly use this issue to read arbitrary memory contents or cause OpenSSL to crash, resulting in a denial of service. (CVE-2023-0286)

 Octavio Galland and Marcel Bhme discovered that OpenSSL incorrectly handled streaming ASN.1 data. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-0215)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libssl1.0-dev, libssl1.0.0 and / or openssl1.0 packages.
