Sensitive data exposure in NATS

Preview versions of two NPM packages and one Deno package from the NATS project contain an information disclosure flaw, leaking options to the NATS server; for one package, this includes TLS private credentials. The connection configuration options in these JavaScript-based implementations were...

CVE-2020-13637

An issue was discovered in the stashcat app through 3.9.2 for macOS, Windows, Android, iOS, and possibly other platforms. It stores the clientkey, the deviceid, and the public key for end-to-end encryption in cleartext, enabling an attacker by copying or having access to the local storage databas...

CVE-2020-13129

An issue was discovered in the stashcat app through 3.9.1 for macOS, Windows, Android, iOS, and possibly other platforms. The GET method is used with clientkey and deviceid data in the query string, which allows attackers to obtain sensitive information by reading web-server logs...

CVE-2016-8635

It was found that Diffie Hellman Client key exchange handling in NSS 3.21.x was vulnerable to small subgroup confinement attack. An attacker could use this flaw to recover private keys by confining the client DH key to small subgroup of the desired group...

SSE-C Cryptographic Flaw

github.com/minio/minio is vulnerable to cryptographic flaws. The vulnerability exists as there is a weakness in the derived key-encryption-key for SSE-C encrypted objects. The vulnerability allows malicious users to replace objects that are encrypted with the same client key as it was not bound t...
