Double Free

Overview Affected versions of this package are vulnerable to Double Free in the OCSP certificate revocation checking process during a TLS handshake with a trusted endpoint. An attacker can cause the client application to terminate unexpectedly by sending specially crafted certificate data that...

DEBIAN-CVE-2026-84964

A double free in the OpenSSL-based TLS certificate revocation checking path of the MongoDB C Driver can be reached by a TLS endpoint that the client already trusts. During the handshake, specially formed certificate data can cause the same heap object to be released twice. An unauthenticated part...

CVE-2026-84964

CVE-2026-84964 is a double free vulnerability in the MongoDB C Driver , specifically in its OpenSSL-based TLS certificate revocation checking path . During a TLS handshake, specially formed certificate data from a crafted multi-URL certificate can cause the same heap object to be released twice. ...

erlang: Erlang SSL: Unauthenticated data injection during TLS handshake

A flaw was found in Erlang's SSL Secure Sockets Layer component. A network-positioned attacker can exploit this vulnerability by injecting unauthenticated plaintext data into a client's TLS Transport Layer Security handshake. The client application may then process this injected data as if it wer...
