Security Bulletin


Summary

OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL is used by IBM Rational ClearCase. IBM Rational ClearCase has addressed the applicable CVEs.

Vulnerability Details

CVEID:   CVE-2022-1292
DESCRIPTION:   OpenSSL could allow a remote authenticated attacker to execute arbitrary commands on the system, caused by improper validation of user-supplied input by the c_rehash script. By sending a specially-crafted request using shell metacharacters, an attacker could exploit this vulnerability to execute arbitrary commands with the privileges of the script on the system.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225619 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)

CVEID:   CVE-2022-0778
DESCRIPTION:   OpenSSL is vulnerable to a denial of service, caused by a flaw in the BN_mod_sqrt() function when parsing certificates. By using a specially-crafted certificate with invalid explicit curve parameters, a remote attacker could exploit this vulnerability to cause an infinite loop, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/221911 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
