  "title": "Libsolv: stack-based buffer overflow in libsolv eddsa pgp signature verification allows denial of service",
  "description": "A flaw was found in libsolv. A stack-based buffer overflow vulnerability exists in the PGP verification component due to incorrect length handling when copying EdDSA \u0027s\u0027 MPI into a stack buffer. A remote attacker could craft a malicious Ed25519 PGP signature with mismatched MPI lengths. Processing this crafted signature could lead to a denial of service in automated package or repository processing workflows.",
