Technical Analysis

CVE-2022-35054 is a medium-severity heap buffer overflow vulnerability identified in the OTFCC project, specifically in the otfccdump binary at the offset /release-x64/otfccdump+0x6171b2. OTFCC (OpenType Font Compression and Conversion) is a tool used for manipulating OpenType font files, often utilized in font development and processing workflows. The vulnerability arises from improper handling of heap memory, leading to a buffer overflow condition (CWE-787). This flaw can be triggered remotely without requiring privileges (AV:N/PR:N), but it does require user interaction (UI:R), such as opening or processing a maliciously crafted font file. The impact is limited to availability (A:H), meaning the vulnerability could cause a denial of service or crash of the otfccdump process, but does not directly compromise confidentiality or integrity. The CVSS 3.1 base score is 6.5, reflecting a medium severity level. No known exploits are currently in the wild, and no patches or vendor advisories have been linked, indicating limited public exposure and mitigation options at this time. The vulnerability is relevant to users and organizations that utilize OTFCC tools in their font processing pipelines or software development environments.

Potential Impact

For European organizations, the primary impact of CVE-2022-35054 is the potential disruption of font processing workflows that rely on OTFCC tools. This could affect graphic design firms, publishing houses, software developers, and any entities involved in font creation or manipulation. A successful exploitation could cause denial of service conditions, leading to application crashes or service interruptions. While the vulnerability does not allow for data exfiltration or code execution, the availability impact could delay critical publishing or software release schedules, especially for organizations with automated font processing pipelines. Given the lack of known exploits, the immediate risk is moderate, but organizations should be aware of the potential for future exploitation if attackers develop reliable attack vectors. Additionally, if OTFCC tools are integrated into larger software systems, the impact could cascade, affecting broader operational stability.

Mitigation Recommendations

Organizations should first inventory their use of OTFCC tools and identify any automated or manual workflows involving otfccdump. Until official patches or updates are released, the following mitigations are recommended: 1) Restrict the processing of untrusted or unauthenticated font files with OTFCC tools to reduce exposure to malicious inputs. 2) Implement sandboxing or containerization for font processing tasks to isolate potential crashes and prevent broader system impact. 3) Monitor for updates from the OTFCC project or related repositories and apply patches promptly once available. 4) Employ runtime protections such as Address Space Layout Randomization (ASLR) and heap protection mechanisms to reduce the likelihood of successful exploitation. 5) Educate users about the risks of opening or processing fonts from unverified sources to minimize user interaction-based triggers. 6) Consider alternative font processing tools with a stronger security track record if OTFCC is not critical to operations.
