Official description

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.

The underlying weakness: Missing Release of Memory after Effective Lifetime

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.

How developers prevent this class of flaw

  • Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone. For example, glibc in Linux provides protection against free of invalid pointers. When using Xcode to target OS X or iOS, enable automatic reference counting (ARC). To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std
  • Use an abstraction library to abstract away risky APIs. Not a complete solution.
  • Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
