OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL is used by IBM Rational ClearQuest. IBM Rational ClearQuest has addressed the applicable CVEs.
CVEID:CVE-2021-23839
**DESCRIPTION:**OpenSSL could provide weaker than expected security, caused by incorrect SSLv2 rollback protection that allows for the inversion of the logic during a padding check. If the server is configured for SSLv2 support at compile time, configured for SSLv2 support at runtime or configured for SSLv2 ciphersuites, it will accept a connection if a version rollback attack has occurred and erroneously reject a connection if a normal SSLv2 connection attempt is made.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196849 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N)
CVEID:CVE-2021-23840
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by an integer overflow in CipherUpdate. By sending an overly long argument, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196848 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)
CVEID:CVE-2021-23841
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the X509_issuer_and_serial_hash() function. By parsing the issuer field, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196847 for the current score.

CVEID:CVE-2020-1971
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference. If the GENERAL_NAME_cmp function contain an EDIPARTYNAME, an attacker could exploit this vulnerability to cause the application to crash.
