Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2019-17006)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Mozilla NSS library when processing input text length while using certain cryptographic primitives. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2019-20444)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to incorrect processing of HTTP headers without the colon within the HttpObjectDecoder.java file in Netty. A remote attacker can send a specially crafted HTTP request to the application and perform HTTP request smuggling attack.
3) HTTP response splitting (CVE-ID: CVE-2019-20445)
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not corrector process CRLF character sequences within the HttpObjectDecoder.java in Netty, which allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2019-16869)
The vulnerability allows a remote attacker to perform HTTP request smuggling attack.
The vulnerability exists due to improper input validation when processing a whitespace before the colon in HTTP headers (e.g. "Transfer-Encoding : chunked"). A remote attacker can send a specially crafted HTTP request and perform HTTP request smuggling attack.
5) Input validation error (CVE-ID: CVE-2019-17195)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Nimbus JOSE+JWT throws various uncaught exceptions while parsing a JWT. A remote attacker can send a specially crafted JWT token and cause the application to crash or potentially bypass authentication.
