FontForge SFD File Parsing Use-After-Free 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 validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-28525.
A flaw was found in FontForge. This use-after-free vulnerability in the SFD file parsing component allows remote attackers to execute arbitrary code. Exploitation requires user interaction, such as opening a specially crafted malicious SFD file or visiting a malicious web page. Successful exploitation can lead to arbitrary code execution in the context of the current user.
Отчет
This vulnerability is rated Important for Red Hat products because it allows remote code execution in FontForge due to a use-after-free flaw during SFD file parsing. Exploitation requires user interaction, specifically opening a specially crafted malicious SFD file or visiting a malicious web page. This affects FontForge in Red Hat Enterprise Linux and Red Hat In-Vehicle OS.
Меры по смягчению последствий
To mitigate this issue, users should avoid opening untrusted SFD files or visiting untrusted web pages that may attempt to exploit this vulnerability. If FontForge is not required, consider removing the fontforge package to eliminate the attack surface. Removing this package may impact functionality that relies on font editing capabilities.
