The NixOS update has some details: https://github.com/NixOS/nixpkgs/pull/198999 https://github.com/NixOS/nixpkgs/pull/198999 ### Changes between 3.0.6 and 3.0.7 [1 Nov 2022] * Fixed two buffer overflows in punycode decoding functions. A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects. An attacker can craft a malicious email address to overflow an arbitrary number of bytes containing the `.` character (decimal 46) on the stack. This buffer overflow could result in a crash (causing a denial of service). ([CVE-2022-3786]) An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution depending on stack layout for any given platform/compiler. ([CVE-2022-3602]) *Paul Dale*
