Affected: fonttools

fontTools is a library for manipulating fonts, written in Python. In versions from 4.33.0 to before 4.60.2, the fonttools varLib (or python3 -m fontTools.varLib) script has an arbitrary file write vulnerability that leads to remote code execution when a malicious .designspace file is processed. The vulnerability affects the main() code path of fontTools.varLib, used by the fonttools varLib CLI and any code that invokes fontTools.varLib.main(). This issue has been patched in version 4.60.2.

Affected: Ubuntu:Pro:22.04:LTS: fonttools, Ubuntu:Pro:24.04:LTS: fonttools, Ubuntu:25.10: fonttools

It was discovered that the subsetting module of fontTools was vulnerable to an XML External Entity (XEE) attack. An unauthenticated remote attacker could possibly use this issue to include arbitrary files from the file system or make web requests from the host system. This issue only affected Ubuntu 22.04 LTS. (CVE-2023-45139)

It was discovered that fontTools was vulnerable to path traversal attacks. If a user or automated system were tricked into extracting a specially crafted .designspace file, an attacker could possibly use this issue to write arbitrary files outside the target directory, resulting in remote code execution. This issue only affected Ubuntu 24.04 LTS, Ubuntu 25.04 and Ubuntu 25.10. (CVE-2025-66034)
