AI risk analysis
- Summary
- The flaw involves an integer overflow in the sprintf() function, leading to potential buffer overflow. This can allow attackers to inject malicious code or cause a denial of service.
- Exploitability
- Exploitation is moderately difficult as it requires precise control over the input to trigger the buffer overflow. The attacker must have network access and knowledge of the specific failure path.
- Blast radius
- If exploited, the impact could be significant, potentially leading to remote code execution or service disruption.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to the fixed version 2.590 or later.

NVD description
The revoked-key error path builds a human-readable failure reason using sprintf() into a heap buffer. The allocated buffer is too small for the final formatted message. When sprintf() writes the full message, it can write past the end of the heap allocation.
