Security Bulletin: Multiple vulnerabilities in Bouncy Castle API affect IBM License Metric Tool.

Summary

IBM License Metric Tool is affected by Bouncy Castle Cryptography vulnerabilities.

Vulnerability Details

CVEID:CVE-2024-30172
**DESCRIPTION:**The Bouncy Castle Crypto Package For Java is vulnerable to a denial of service, caused by an infinite loop in the Ed25519 verification code. By persuading a victim to use a specially crafted signature and public key, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/290103 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID:CVE-2024-29857
**DESCRIPTION:**The Bouncy Castle Crypto Package For Java is vulnerable to a denial of service, caused by improper input validation. By importing an EC certificate with crafted F2m parameters, a remote attacker could exploit this vulnerability to cause excessive CPU consumption.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/290285 for the current score.
