Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you. ## Technical details The vulnerability exists in the error handling path for revoked keys, where sprintf() writes a formatted error message into a heap-allocated buffer that is too small to hold the complete output, resulting in a heap buffer overflow. The insufficient buffer allocation allows an attacker to overwrite adjacent heap memory, potentially leading to code execution or denial of service depending on heap layout and mitigations present. ## Affected products - Fortra ## Timeline - 2026-10-01: disclosed ## References - [https://www.fortra.com/security/advisories/product-security/fi-2026-019](https://www.fortra.com/security/advisories/product-security/fi-2026-019)
