Summary

IBM Spectrum Protect Plus File Systems Agent can be affected by vulnerability in PyPI cryptography and Python. Vulnerabilities could allow a remote attacker to bypass security restrictions or do a denial of service attack, as described by the CVEs in the “Vulnerability Details” section.

Vulnerability Details

CVEID:CVE-2023-23931
**DESCRIPTION:**PyPI cryptography package could allow a remote attacker to bypass security restrictions, caused by a memory corruption in Cipher.update_into. By passing an immutable python object as the outbuf, an attacker could exploit this vulnerability to bypass authentication and obtain access.
CVSS Base score: 4.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246738 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L)

CVEID:CVE-2023-24329
**DESCRIPTION:**Python could allow a remote attacker to bypass security restrictions, caused by a flaw in the urllib.parse component. By sending a specially-crafted request using URL starts with blank characters, an attacker could exploit this vulnerability to bypass blocklisting methods.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/247730 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID:CVE-2023-0286
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a type confusion error related to X.400 address processing inside an X.509 GeneralName. By passing arbitrary pointers to a memcmp call, a remote attacker could exploit this vulnerability to read memory contents or cause a denial of service.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246611 for the current score.
