A heap-buffer-overflow read vulnerability has been identified in versions 1.1.1 and earlier. The vulnerability, tracked as CVE-2026-35176, resides in the \u003ccode\u003ePOFParser::parseSection()\u003c/code\u003e function. It allows an attacker to trigger out-of-bounds heap memory access by supplying a specially crafted \u003ccode\u003e.pof\u003c/code\u003e file. Critically, exploiting this vulnerability does not require any specific FPGA hardware, making it easier to trigger. Successful exploitation could lead to denial of service or information disclosure.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker crafts a malicious \u003ccode\u003e.pof\u003c/code\u003e file designed to trigger the heap-buffer-overflow.\u003c/li\u003e\n\u003cli\u003eThe attacker delivers the malicious \u003ccode\u003e.pof\u003c/code\u003e file to a system running a vulnerable version of openFPGALoader (\u0026lt;= 1.1.1).\u003c/li\u003e\n\u003cli\u003eA user or automated process attempts to parse the malicious \u003ccode\u003e.pof\u003c/code\u003e file using openFPGALoader.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003ePOFParser::parseSection()\u003c/code\u003e function is called to process a section of the \u003ccode\u003e.pof\u003c/code\u003e file.\u003c/li\u003e\n\u003cli\u003eDue to the crafted structure of the \u003ccode\u003e.pof\u003c/code\u003e file, the \u003ccode\u003eparseSection()\u003c/code\u003e function attempts to read beyond the allocated heap buffer.\u003c/li\u003e\n\u003cli\u003eThis out-of-bounds read operation causes the program to potentially crash (denial of service) or leak sensitive information from adjacent memory locations.\u003c/li\u003e\n\u003cli\u003eIf information disclosure occurs, the attacker may gain insights into the system\u0026rsquo;s memory layout or potentially extract sensitive data.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability can lead to a denial-of-service condition, causing the openFPGALoader application to crash.
