Use of Uninitialized Variable

CVE-2024-9355

Severity Medium
Score 6.5/10

Summary

A vulnerability was found in github.com/golang-fips/openssl package. 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.
