Description Vladimir Vasilev 2026-10-13 07:35:06 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A vulnerability was determined in Konstanty Bialkowski libmodplug up to 0.8.9.1. This issue affects the function abc_add_gchord of the file src/load_abc.cpp of the component ABC Music Format Parser. This manipulation causes resource consumption. The attack may be initiated remotely. The vendor was contacted early about this disclosure but did not respond in any way.
