-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 =========================================================================== AUSCERT Security Bulletin ASB-2019.0290 Multiple vulnerabilities have been identified in Oracle GraalVM 16 October 2019 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Oracle GraalVM Operating System: Windows UNIX variants (UNIX, Linux, OSX) Impact/Access: Modify Arbitrary Files -- Remote/Unauthenticated Denial of Service -- Remote/Unauthenticated Resolution: Patch/Upgrade CVE Names: CVE-2019-9511 CVE-2019-2989 CVE-2019-2986 Member content until: Friday, November 15 2019 Reference: ASB-2019.0238 ESB-2019.3845 ESB-2019.3782 ESB-2019.3748 OVERVIEW Multiple vulnerabilities have been identified in : o Oracle GraalVM Enterprise Edition, version 19.2.0  IMPACT The vendor has provided the following information regarding the vulnerabilities: "This Critical Patch Update contains 3 new security patches for Oracle GraalVM. 2 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials."  "CVE-2019-2986 7.7 AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise Oracle GraalVM Enterprise Edition. While the vulnerability is in Oracle GraalVM Enterprise Edition, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle GraalVM Enterprise Edition. Affects: o Oracle GraalVM Enterprise Edition 19.2.0 CVE-2019-9511 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle GraalVM Enterprise Edition. Affects: o Oracle GraalVM Enterprise Edition 19.2.0 CVE-2019-2989 6.8 AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle GraalVM Enterprise Edition. While the vulnerability is in Oracle GraalVM Enterprise Edition, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle GraalVM Enterprise Edition accessible data. Affects: o Oracle GraalVM Enterprise Edition 19.2.0"  MITIGATION Oracle states: "Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. Until you apply the CPU fixes, it may be possible to reduce the risk of successful attack by blocking network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Both approaches may break application functionality, so Oracle strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem."
