CVE-2024-9355

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.

What the metrics mean

  • It is requires local access to the machine.
  • For an attacker who can reach it, exploitation depends on conditions outside the attacker's control.
  • To exploit it, an ordinary user account is needed.
  • Beyond that, no action by a user is required.
