According to the versions of the libsndfile package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • The psf_fwrite function in file_io.c in libsndfile allows attackers to cause a denial of service (divide-by-zero error and application crash) via unspecified vectors related to the headindex variable.(CVE-2014-9756)

  • Heap-based Buffer Overflow in the psf_binheader_writef function in common.c in libsndfile through 1.0.28 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.(CVE-2017-12562)

  • 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)

  • 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.(CVE-2017-16942)

  • In libsndfile before 1.0.28, an error in the ‘flac_buffer_copy()’ function (flac.c) can be exploited to cause a stack-based buffer overflow via a specially crafted FLAC file.(CVE-2017-7585)

  • In libsndfile before 1.0.28, an error in the ‘header_read()’ function (common.c) when handling ID3 tags can be exploited to cause a stack-based buffer overflow via a specially crafted FLAC file.(CVE-2017-7586)

  • In libsndfile before 1.0.28, an error in the ‘flac_buffer_copy()’ function (flac.c) can be exploited to cause a segmentation violation (with write memory access) via a specially crafted FLAC file during a resample attempt, a similar issue to CVE-2017-7585.(CVE-2017-7741)

  • In libsndfile before 1.0.28, an error in the ‘flac_buffer_copy()’ function (flac.c) can be exploited to cause a segmentation violation (with read memory access) via a specially crafted FLAC file during a resample attempt, a similar issue to CVE-2017-7585.(CVE-2017-7742)
