CVE-2024-9355 - OpenSSL FIPS Uninitialized Buffer Length and HMAC Sum Calculation Vulnerability in Golang

CVE ID : CVE-2024-9355
Published : Oct. 1, 2024, 7:15 p.m. | 24 minutes ago
Description : 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.
Severity: 6.5 | MEDIUM
