The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6313-1 advisory.

    It was discovered that FAAD2 incorrectly handled certain inputs. If a user or an automated system were     tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to     execute arbitrary code. (CVE-2021-32272, CVE-2021-32273, CVE-2021-32274, CVE-2021-32277, CVE-2021-32278,     CVE-2023-38857, CVE-2023-38858)

    It was discovered that FAAD2 incorrectly handled certain inputs. If a user or an automated system were     tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to     cause a denial of service. (CVE-2021-32276)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5109 advisory.

  - There is a stack-based buffer overflow 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 the S_M array is mishandled.
    (CVE-2018-20196)

  - A NULL pointer dereference was discovered in ifilter_bank of libfaad/filtbank.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 because adding to windowed output is mishandled in the ONLY_LONG_SEQUENCE case.
    (CVE-2018-20199)

  - An invalid memory address dereference was discovered in the sbr_process_channel function of     libfaad/sbr_dec.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-2018-20360)

  - An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. It is a buffer over-read in     ps_mix_phase in libfaad/ps_dec.c. (CVE-2019-6956)
