CVE-2026-3994 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the initialize_sections() function of the Object File Handler. An attacker can execute arbitrary code or cause a denial of service by providing specially crafted object files to the application during local processing.
Note:
This issue was rejected by the vendor with the following reasoning: "However, we do actually trust input object files, so the behavior when you fed hand-crafted corrupted object files is not guaranteed in any way. It may do out-of-bound memory access, but we accept that. This is not a bug per our policy."
