* golang: golang-fips/openssl: Memory leaks in code encrypting and decrypting RSA payloads (CVE-2024-1394)

A memory leak flaw was found in Golang in the RSA encrypting/decrypting code, which might lead to a resource exhaustion vulnerability using attacker-controlled inputs​. The memory leak happens in github.com/golang-fips/openssl/openssl/rsa.go#L113. The objects leaked are pkey​ and ctx​. That function uses named return parameters to free pkey​ and ctx​ if there is an error initializing the context or setting the different properties. All return statements related to error cases follow the "return nil, nil, fail(...)" pattern, meaning that pkey​ and ctx​ will be nil inside the deferred function that should free them.

Affected: Go: github.com/golang-fips/go, Go: github.com/golang-fips/openssl/v2, Go: github.com/microsoft/go-crypto-openssl, Go: github.com/microsoft/go-crypto-openssl/openssl

Using crafted public RSA keys which are not compliant with SP 800-56B can cause a small memory leak when encrypting and verifying payloads.

An attacker can leverage this flaw to gradually erode available memory to the point where the host crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service.
