Summary

Bouncy Castle as used by IBM QRadar SIEM contains multiple vulnerabilities

Vulnerability Details

CVEID:CVE-2018-1000613
**DESCRIPTION:**Legion of the Bouncy Castle Java Cryptography APIs could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe reflection flaw in XMSS/XMSS^MT private key deserialization. By using specially-crafted private key, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/148041 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2017-13098
**DESCRIPTION:**Bouncy Castle could allow a remote attacker to obtain sensitive information, caused by an RSA Adaptive Chosen Ciphertext (Bleichenbacher) attack. By utilizing discrepancies in TLS error messages, an attacker could exploit this vulnerability to obtain the data in the encrypted messages once the TLS session has completed. Note: This vulnerability is also known as the ROBOT attack.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/136241 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2018-1000180
**DESCRIPTION:**Bouncy Castle could provide weaker than expected security, caused by an error in the Low-level interface to RSA key pair generator. The RSA Key Pairs generated in low-level API with added certainty may have less M-R tests than expected. An attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/144810 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
