Description A latent issue in the Prio library may cause data to be read from uninitialized memory for some functions, potentially leading to memory corruption. The vulnerability is related to a buffer overflow in memory, which could allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.
