Security Bulletin
Summary
A critical OpenSSL buffer overflow vulnerability and possible denial of service affect IBM Watson Explorer Foundational Components. IBM Watson Explorer Foundational Components has addressed the vulnerabilities by updating the version of OpenSSL.
Vulnerability Details
CVEID: CVE-2021-3712
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds read when processing ASN.1 strings. By sending specially crafted data, an attacker could exploit this vulnerability to read contents of memory on the system or perform a denial of service attack.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/208073 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L)
CVEID: CVE-2021-3711
DESCRIPTION: OpenSSL is vulnerable to a buffer overflow, caused by improper bounds checking by the EVP_PKEY_decrypt() function within implementation of the SM2 decryption. By sending specially crafted SM2 content, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/208072 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)
