CVEID:CVE-2023-4807
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a state corruption flaw in the POLY1305 MAC (message authentication code) implementation, when running on newer X86_64 processors supporting the AVX512-IFMA instructions. A local authenticated attacker could exploit this vulnerability to cause an incorrect result of some application dependent calculations or a crash or in some cases gain complete control of the application process.

CVEID:CVE-2023-5676
**DESCRIPTION:**Eclipse OpenJ9 is vulnerable to a denial of service, caused by a flaw when a shutdown signal (SIGTERM, SIGINT or SIGHUP) is received before the JVM has finished initializing. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause an infinite busy hang on a spinlock or a segmentation fault.
CVSS Base score: 4.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/271615 for the current score.
