CVE-2022-35028: n/a in n/a
OTFCC commit 617837b was discovered to contain a segmentation violation via /release-x64/otfccdump+0x4fbbb6.
AI Analysis
Technical Summary
CVE-2022-35028 is a medium-severity vulnerability identified in the OTFCC project, specifically related to a segmentation violation occurring in the otfccdump binary at the offset +0x4fbbb6. OTFCC (OpenType Font C Compiler) is a tool used for compiling and dumping OpenType font files. The vulnerability is classified under CWE-787, which corresponds to out-of-bounds write errors, indicating that the issue arises from improper memory handling leading to a segmentation fault. The CVSS v3.1 score of 6.5 reflects a medium impact, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact is limited to availability (A:H), meaning the vulnerability can cause a denial of service by crashing the application but does not affect confidentiality or integrity. No known exploits are currently reported in the wild, and no patches or vendor information are provided, suggesting that this vulnerability may affect specific versions or forks of the OTFCC tool, but exact affected versions are not specified. The segmentation violation likely occurs when processing crafted or malformed font files, which could be delivered via email attachments or downloaded content, triggering a crash when the vulnerable tool processes the file. Since the vulnerability requires user interaction, exploitation would typically involve convincing a user to open or process a malicious font file using the vulnerable tool.
Potential Impact
For European organizations, the primary impact of CVE-2022-35028 is the potential for denial of service in environments where OTFCC tools are used to process OpenType fonts. This could disrupt workflows in graphic design, publishing, or software development sectors that rely on font compilation or analysis. Although the vulnerability does not compromise confidentiality or integrity, service interruptions could lead to operational delays and productivity losses. Organizations that integrate OTFCC into automated font processing pipelines or CI/CD systems may experience cascading failures if the vulnerability is triggered. Given the lack of known exploits and the requirement for user interaction, the risk of widespread exploitation is currently low. However, targeted attacks against organizations heavily dependent on font processing tools could leverage this vulnerability to disrupt services. Additionally, if the tool is used in security-sensitive environments or as part of font validation in document processing, denial of service could impact availability of critical services.
Mitigation Recommendations
To mitigate CVE-2022-35028, European organizations should first identify any use of OTFCC tools within their environments, including development, testing, and production systems. Since no official patches are currently available, organizations should consider the following specific actions: 1) Avoid processing untrusted or unauthenticated font files with OTFCC until a patch is released. 2) Implement strict input validation and sandboxing when handling font files to limit the impact of potential crashes. 3) Monitor and restrict user permissions to prevent unauthorized execution of font processing tools. 4) Employ application whitelisting and endpoint protection to detect abnormal crashes or behavior associated with otfccdump. 5) Engage with the OTFCC project or community to track patch releases or updates addressing this vulnerability. 6) For automated pipelines, introduce error handling and fallback mechanisms to prevent cascading failures if the tool crashes. 7) Educate users about the risks of opening or processing font files from untrusted sources, emphasizing the need for caution and verification.
