Description

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

  • 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-2017-17457)

  • 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-2017-17456)

  • 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)

  • There is a heap-based buffer over-read at wav.c in wav_write_header in libsndfile 1.0.28 that will cause a denial of service.(CVE-2018-19758)

  • 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-2018-19661)

  • An issue was discovered in libsndfile 1.0.28. There is a NULL pointer dereference in the function sf_write_int in sndfile.c, which will lead to a denial of service.(CVE-2018-19432)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
