Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2019-1559)
The vulnerability allows a remote attacker to decrypt sensitive information.
The vulnerability exists due to the way an application behaves, when it receives a 0-byte record with invalid padding compared to the record with an invalid MAC, which results in padding oracle. A remote attacker can decrypt data.
Successful exploitation of the vulnerability requires that the application is using "non-stitched" ciphersuites and calls SSL_shutdown() twice (first, via a BAD_RECORD_MAC and again via a CLOSE_NOTIFY).2) Input validation error (CVE-ID: CVE-2018-19362)
The disclosed vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code.
The vulnerability exists due to fail to block the jboss-common-coreclass from polymorphic deserialization. A remote attacker can send a specially crafted request that submits malicious input to perform unauthorized actions on the system, which could allow the attacker to execute arbitrary code or cause a denial of service (DoS) condition.
3) Deserialization of untrusted data (CVE-ID: CVE-2017-5645)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists receiving serialized log events from another application when using the TCP socket server or UDP socket server. A remote attacker can submit a specially crafted binary payload, when deserialized, and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
