Description

A vulnerability in OpenSSL's RSASVE key encapsulation implementation can cause applications to disclose sensitive data from uninitialized memory when processing attacker-supplied invalid RSA public keys. This issue affects applications using the EVP_PKEY_encapsulate() function without proper validation of the RSA public key. The vulnerability has a moderate impact and no current mitigation meets Red Hat's criteria for ease of use and applicability. An update including openssl-fips-provider-3.0.7-1.2.hum1 packages has been released by Red Hat as a bug fix and enhancement update.
