From 2.0.0 until 2.3.0, an M4A file containing a sub-atom with a size of zero inside a ---- atom can cause the metadata parser to stop advancing through the input. The custom-field atom traversal repeatedly processes the malformed location, causing an infinite loop and denying service to a program that reads the crafted file. This issue is fixed in version 2.3.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-835"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tinytag/tinytag/commit/9ada221ba44990cb02cd9002d992186e037b515e","tags":[]},{"url":"https://github.com/tinytag/tinytag/pull/326","tags":[]},{"url":"https://github.com/tinytag/tinytag/releases/tag/2.3.0","tags":[]},{"url":"https://github.com/tinytag/tinytag/security/advisories/GHSA-24cc-9352-h2pg","tags":[]}],"exploitRefs":[{"url":"https://github.com/tinytag/tinytag/commit/9ada221ba44990cb02cd9002d992186e037b515e","tags":[]},{"url":"https://github.com/tinytag/tinytag/pull/326","tags":[]},{"url":"https://github.com/tinytag/tinytag/releases/tag/2.3.0","tags":[]},{"url":"https://github.com/tinytag/tinytag/security/advisories/GHSA-24cc-9352-h2pg","tags":[]}],"hasPoc":true,"ai":null}
