Multiple vulnerabilities in OpenSSL used by IBM InfoSphere Information Server were addressed.
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)
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.
