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.
