Technical Analysis

CVE-2022-35067 is a medium severity heap buffer overflow vulnerability identified in a specific commit (617837b) of the OTFCC project, which is a toolset related to OpenType font manipulation. The vulnerability occurs in the binary component referenced as /release-x64/otfccdump at an offset of 0x6e41b0. A heap buffer overflow (CWE-787) typically allows an attacker to overwrite adjacent memory on the heap, which can lead to application crashes or potentially enable arbitrary code execution if exploited correctly. According to the CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H), the vulnerability can be exploited remotely over the network without privileges but requires user interaction. The impact is limited to availability (denial of service) with no direct confidentiality or integrity compromise indicated. No known exploits are currently reported in the wild, and no patches or vendor details are provided, indicating that this vulnerability may affect open-source or less widely distributed tooling rather than a commercial product. The lack of specific product or version information limits precise identification of affected environments, but the vulnerability is associated with a font manipulation tool, which may be used in software development, font processing, or document rendering pipelines.

Potential Impact

For European organizations, the primary impact of CVE-2022-35067 would be service disruption or denial of service in environments that utilize the OTFCC toolset or related font processing utilities. This could affect software development firms, digital publishing houses, graphic design companies, or any enterprise that integrates OpenType font manipulation in their workflows. While the vulnerability does not directly compromise data confidentiality or integrity, denial of service could interrupt critical font rendering or document processing tasks, potentially delaying operations or impacting user experience. Given the medium severity and requirement for user interaction, the risk is moderate but should not be ignored, especially in sectors relying heavily on automated font processing or document generation. The absence of known exploits reduces immediate threat but does not preclude future exploitation, particularly if attackers develop techniques to leverage this heap overflow for code execution.

Mitigation Recommendations

Organizations should first identify whether OTFCC or related font manipulation tools are in use within their environments. If so, they should monitor the official OTFCC repositories or security advisories for patches or updates addressing this vulnerability. In the absence of an official patch, consider applying manual code audits or runtime protections such as heap overflow detection mechanisms (e.g., AddressSanitizer) during development and testing. Restricting the execution of untrusted font files or limiting user interaction with potentially vulnerable components can reduce exploitation likelihood. Employ application whitelisting and sandboxing for font processing tools to contain potential crashes or exploits. Additionally, implement robust logging and monitoring to detect abnormal application behavior indicative of exploitation attempts. Finally, educate users about the risks of interacting with untrusted font files or documents that may trigger the vulnerability.
