How to Fix CVE-2024-9355

To remediate this vulnerability, upgrade all affected Github.com/golang fips/openssl dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/golang-fips/openssl fixed: Latest secure release 
Upgrade github.com/golang-fips/openssl to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/golang-fips/openssl

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-9355, inspect your project dependencies for Github.com/golang fips/openssl:

inspect dependencies for github.com/golang-fips/openssl

Analyze the terminal output to locate any version of Github.com/golang fips/openssl in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-457: Use of Uninitialized Variable, where the code uses a variable that has not been initialized, leading to unpredictable or unintended results. In Github.com/golang fips/openssl, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.  It is also possible to force a derived key to be all zeros instead of an unpredictable value.  This may have follow-on implications for the Go TLS stack.
