USN-4083-1: OpenJDK 11 vulnerabilities

First published: Wed Jul 31 2019(Updated: )

It was discovered that OpenJDK did not sufficiently validate serial streams before deserializing suppressed exceptions in some situations. An attacker could use this to specially craft an object that, when deserialized, would cause a denial of service. (CVE-2019-2762) It was discovered that in some situations OpenJDK did not properly bound the amount of memory allocated during object deserialization. An attacker could use this to specially craft an object that, when deserialized, would cause a denial of service (excessive memory consumption). (CVE-2019-2769) It was discovered that OpenJDK did not properly restrict privileges in certain situations. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions. (CVE-2019-2786) Jonathan Birch discovered that the Networking component of OpenJDK did not properly validate URLs in some situations. An attacker could use this to bypass restrictions on characters in URLs. (CVE-2019-2816) It was discovered that the ChaCha20Cipher implementation in OpenJDK did not use constant time computations in some situations. An attacker could use this to expose sensitive information. (CVE-2019-2818) It was discovered that the Java Secure Socket Extension (JSSE) component in OpenJDK did not properly handle OCSP stapling messages during TLS handshake in some situations. An attacker could use this to expose sensitive information. (CVE-2019-2821) It was discovered that OpenJDK incorrectly handled certain memory operations. If a user or automated system were tricked into opening a specially crafted PNG file, a remote attacker could use this issue to cause OpenJDK to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2019-7317)
