High [CVE-2024-1394] Golang-fips/openssl: memory leaks in code encrypting and decrypting rsa payloads

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 majority of RHEL utilities are not long-running applications; instead, they are command-line tools.

These tools utilize Golang package as build-time dependency, which is why they are classified as having a "Moderate" level of impact. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

Weakness: CWE-401.

Affected products named by the advisory: Red Hat Ansible Automation Platform 2.4 for RHEL 8; Red Hat Ansible Automation Platform 2.4 for RHEL 9; Red Hat Developer Tools; Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions; and 37 more.
