An invalid memory address dereference was discovered in the hf_assembly function of libfaad/sbr_hfadj.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An invalid memory address dereference was discovered in the hf_assembly function of libfaad/sbr_hfadj.c in     Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. The vulnerability causes a segmentation fault and     application crash, which leads to denial of service. (CVE-2018-20361)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. The faad_resetbits function in
    libfaad/bits.c is affected by a buffer overflow vulnerability. The number of bits to be read is determined
    by ld->buffer_size - words*4, cast to uint32. If ld->buffer_size - words*4 is negative, a buffer overflow
    is later performed via getdword_n(&ld->start[words], ld->bytes_left). (CVE-2019-15296)

  - An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.1. There was a heap-based buffer
    overflow in the function excluded_channels() in libfaad/syntax.c. (CVE-2018-19502)

  - An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.1. There was a stack-based buffer
    overflow in the function calculate_gain() in libfaad/sbr_hfadj.c. (CVE-2018-19503)

  - An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.1. There is a NULL pointer
    dereference in ifilter_bank() in libfaad/filtbank.c. (CVE-2018-19504)

  - There is a stack-based buffer underflow in the third instance of the calculate_gain function in
    libfaad/sbr_hfadj.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. A crafted input will lead to a
    denial of service or possibly unspecified other impact because limiting the additional noise energy level
    is mishandled for the G_max <= G case. (CVE-2018-20194)

The remote host is affected by the vulnerability described in GLSA-202006-17 (FAAD2: Multiple vulnerabilities)
