CVE-2017-16942

In libsndfile 1.0.25 (fixed in 1.0.26), a divide-by-zero error exists in the function wav_w64_read_fmt_chunk() in wav_w64.c, which may lead to DoS when playing a crafted audio file.

An out of bounds read in the function d2alaw_array() in alaw.c of libsndfile 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values (CVE-2017-14245).

An out of bounds read in the function d2ulaw_array() in ulaw.c of libsndfile 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values (CVE-2017-14246).

In libsndfile 1.0.28, a divide-by-zero error exists in the function double64_init() in double64.c, which may lead to DoS when playing a crafted audio file (CVE-2017-14634).

Divide-by-zero in the function wav_w64_read_fmt_chunk(), which may lead to Denial of service (CVE-2017-16942).

Note that CVE-2017-16942 only affected Mageia 5.
