Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2018-0732)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to improper handling of large prime values by the affected software during key agreement operations in a Transport Layer Security (TLS) handshake using an Ephemeral Diffie-Hellman (DHE) based cipher suite. A remote attacker can send a large prime value from a malicious OpenSSL server to a targeted OpenSSL client and cause the client to stop responding while generating a key for the prime value.


2) Resource exhaustion (CVE-ID: CVE-2018-0739)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to excessive stack memory consumption. A remote attacker can cause the service to crash.
