gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...

CVE-2026-48697

FastNetMon Community Edition through 1.2.9 does not verify TLS certificates on outbound HTTPS connections. The executewebrequestsecure function in src/fastlibrary.cpp creates a boost::asio::ssl::context with tlsclient mode and calls setdefaultverifypaths to load CA certificates, but never calls...

CVE-2026-48697

Summary: CVE-2026-48697 affects FastNetMon Community Edition up to 1.2.9. The root cause is in execute_web_request_secure() in src/fast_library.cpp, which creates a Boost.Asio TLS client context (tls_client) and calls set_default_verify_paths() but never enables verify_peer. As a result, OpenSSL ...

PT-2026-47001

An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutl...
