"Secunia reports :

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."
