CVE-2025-68617 (CNNVD-202512-4024)
中文标题:
fluidsynth 资源管理错误漏洞
英文标题:
Use after free in fluidsynth
漏洞描述
中文描述:
fluidsynth是fluidsynth开源的一个应用系统。用于通过使用SoundFont通过读取和处理MIDI输入设备中的MIDI事件来生成音频。 fluidsynth 2.5.2之前版本存在资源管理错误漏洞，该漏洞源于卸载DLS文件时存在竞争条件，可能触发基于堆的释放后重用。
英文描述:
FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From versions 2.5.0 to before 2.5.2, a race condition during unloading of a DLS file can trigger a heap-based use-after-free. A concurrently running thread may be pending to unload a DLS file, leading to use of freed memory, if the synthesizer is being concurrently destroyed, or samples of the (unloaded) DLS file are concurrently used to synthesize audio. This issue has been patched in version 2.5.2. The problem will not occur, when explicitly unloading a DLS file (before synth destruction), provided that at the time of unloading, no samples of the respective file are used by active voices. The problem will not occur in versions of FluidSynth that have been compiled without native DLS support.
