FreeBSD : OpenSSL -- Multiple vulnerabilities (21f505f4-6a1c-11ef-b611-84a93843eb75)

critical Nessus Plugin ID 206514

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 21f505f4-6a1c-11ef-b611-84a93843eb75 advisory.

The OpenSSL project reports:
Possible denial of service in X.509 name checks [Moderate severity] Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address resulting in abnormal termination of the application process.
SSL_select_next_proto buffer overread [Low severity] Calling the OpenSSL API function SSL_select_next_proto with an empty supported client protocols buffer may cause a crash or memory contents to be sent to the peer.

Tenable has extracted the preceding description block directly from the FreeBSD 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 packages.
