Description	Hossein Lotfi has discovered a vulnerability in libsndfile, which can be exploited by malicious people to potentially compromise an application using the library. The vulnerability is caused due to an integer overflow error in the "paf24_init()" function (src/paf.c) when processing Paris Audio (PAF) files. This can be exploited to cause a heap-based buffer overflow via a specially crafted file. Successful exploitation may allow execution of arbitrary code. The vulnerability is confirmed in version 1.0.24. Other versions may also be affected.
