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).

The version of python installed on the remote host is prior to 2.7.18-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2744 advisory.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:3470-1 advisory.

    - CVE-2024-6923: Fixed uncontrolled CPU resource consumption when in http.cookies module (bsc#1228780).
    - CVE-2024-5642: Fixed buffer overread when NPN is used and invalid values are sent to the OpenSSL API     (bsc#1227233).
    - CVE-2024-7592: Fixed Email header injection due to unquoted newlines (bsc#1229596).
    - CVE-2024-6232: excessive backtracking when parsing tarfile headers leads to ReDoS. (bsc#1230227)

    Bug fixes:

    - %{profileopt} variable is set according to the variable %{do_profiling} (bsc#1227999).
    - Stop using %%defattr, it seems to be breaking proper executable attributes on /usr/bin/ scripts     (bsc#1227378).
    - Remove %suse_update_desktop_file macro as it is not useful any more.
