Updated libvorbis packages fix security vulnerabilities

The updated packages fix security vulnerabilities: The bark_noise_hybridmp function in psy.c in Xiph.Org libvorbis 1.3.5 allows remote attackers to cause a denial of service (out-of-bounds access and application crash) or possibly have unspecified other impact via a crafted mp4 file. (CVE-2017-14160) mapping0_forward in mapping0.c in Xiph.Org libvorbis 1.3.6 does not validate the number of channels, which allows remote attackers to cause a denial of service (heap-based buffer overflow or over-read) or possibly have unspecified other impact via a crafted file. (CVE-2018-10392) bark_noise_hybridmp in psy.c in Xiph.Org libvorbis 1.3.6 has a stack-based buffer over-read. (CVE-2018-10393)
