Security Bulletin: Multiple vulnerabilities in Python may affect the IBM Storage Scale System

Summary

Multiple security vulnerabilities have been identified in IBM Storage Scale System where Python is vulnerable to denial of service. Fixes for these vulnerabilities are available.

Vulnerability Details

CVEID:CVE-2022-45061
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by an unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder. By sending a specially-crafted input, a remote attacker could exploit this vulnerability to cause a CPU denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240593 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-2020-10735
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by the failure to limit amount of digits converting text to int by the int() type in PyLong_FromString(). A remote attacker could exploit this vulnerability to consume all available resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235840 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-2023-40217
**DESCRIPTION:**Python could allow a remote attacker to bypass security restrictions, caused by a race condition in the SSLSocket module. When the socket is closed before the TLS handshake is complete, the data is treated as if it had been encrypted by TLS. An attacker could exploit this vulnerability to bypass the TLS handshake and inject a malicious client certificate into the connection and gain access to the server’s resources without being authenticated.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/264374 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)
