CVE-2024-5642 – CPython 3.9 and earlier doesn’t disallow configuri

CVE ID : CVE-2024-5642

Published : June 27, 2024, 9:15 p.m. | 17 hours, 5 minutes ago

Description : CPython 3.9 and earlier doesn’t disallow configuring an empty list (“[]”) for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured).

Severity: 0.0 | NA
