Peter Korsgaard 45014da2b7 package/libsndfile: add upstream post-1.0.28 security fixes
Fixes the following security vulnerabilities:

CVE-2017-14634: 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-2017-17456: The function d2alaw_array() in alaw.c of libsndfile
1.0.29pre1 may lead to a remote DoS attack (SEGV on unknown address
0x000000000000), a different vulnerability than CVE-2017-14245

CVE-2017-17457: The function d2ulaw_array() in ulaw.c of libsndfile
1.0.29pre1 may lead to a remote DoS attack (SEGV on unknown address
0x000000000000), a different vulnerability than CVE-2017-14246

CVE-2018-13139: A stack-based buffer overflow in psf_memset in common.c in
libsndfile 1.0.28 allows remote attackers to cause a denial of service
(application crash) or possibly have unspecified other impact via a crafted
audio file.  The vulnerability can be triggered by the executable
sndfile-deinterleave

CVE-2018-19661: An issue was discovered in libsndfile 1.0.28.  There is a
buffer over-read in the function i2ulaw_array in ulaw.c that will lead to a
denial of service

CVE-2018-19662: An issue was discovered in libsndfile 1.0.28.  There is a
buffer over-read in the function i2alaw_array in alaw.c that will lead to a
denial of service
