A vulnerability has been identified in libfishsound, which could be exploited by attackers to cause a denial of service or compromise an affected system. This issue is caused by an input validation error in the "process_header()" [src/libfishsound/speex.c] function that does not properly handle negative "modeID" values in the header structure, which could be exploited by attackers to execute arbitrary code via a specially crafted Speex stream.
