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 Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
