FontForge PFB File Parsing Stack-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 PFB files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-28546.
A flaw was found in FontForge. This stack-based buffer overflow vulnerability occurs during the parsing of PFB (Printer Font Binary) files due to improper validation of user-supplied data length. A remote attacker could exploit this by convincing a user to open a specially crafted malicious PFB file, leading to arbitrary code execution in the context of the current user.
Отчет
This vulnerability is rated Important for Red Hat products as it allows remote code execution in FontForge through a stack-based buffer overflow when processing specially crafted PFB files. Exploitation requires user interaction, where a user must open a malicious PFB file. This affects FontForge as shipped in Fedora and Red Hat Enterprise Linux versions where FontForge is available.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
