cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Calling `load_pem_pkcs7_certificates` or `load_der_pkcs7_certificates` could lead to a NULL-pointer dereference and segfault. Exploitation of this vulnerability poses a serious risk of Denial of Service (DoS) for any application attempting to deserialize a PKCS7 blob/certificate. The consequences extend to potential disruptions in system availability and stability. This vulnerability has been patched in version 41.0.6.Show less

An issue was discovered in OpenNDS Captive Portal before version 10.1.2. It has a do_binauth NULL pointer dereference that be triggered with a crafted GET HTTP request with a missing User-Agent HTTP header. Triggering this issue results in crashing OpenNDS (a Denial-of-Service condition). The issue occurs when the client is about to be authenticated, and can be triggered only when the BinAuth option is set. Affected OpenNDS Captive Portal before version 10.1.2 fixed in OpenWrt master, OpenWrt 23.05 and OpenWrt 22.03 on 28. August 2023 by updating OpenNDS to version 10.1.3.Show less
