FontForge SFD File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of FontForge. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SFD files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-28544.
A heap-based buffer overflow vulnerability has been identified in FontForge, specifically within the SFD file parsing process. This vulnerability allows remote attackers to execute arbitrary code on affected installations of FontForge. Exploitation requires user interaction, as the target must open a malicious SFD file. The vulnerability arises from inadequate validation of user-supplied data length before it is copied to a heap-based buffer, enabling attackers to execute code in the context of the current user.
Due to the nature of this vulnerability, the recommended mitigation strategy is to limit interactions with the product.
