CVE-2024-5642
Publication date 27 June 2024
Last updated 29 July 2024
Ubuntu priority
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).
Why is this CVE low priority?
Requires unlikely API usage to be vulnerable.
