Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2792 advisory.

- 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)

- An issue was discovered in faad2 through 2.10.0. A heap-buffer-overflow exists in the function sbr_qmf_synthesis_64 located in sbr_qmf.c. It allows an attacker to cause code Execution. (CVE-2021-32274)

- An issue was discovered in faad2 through 2.10.0. A NULL pointer dereference exists in the function get_sample() located in output.c. It allows an attacker to cause Denial of Service. (CVE-2021-32276)

- An issue was discovered in faad2 through 2.10.0. A heap-buffer-overflow exists in the function sbr_qmf_analysis_32 located in sbr_qmf.c. It allows an attacker to cause code Execution. (CVE-2021-32277)

- An issue was discovered in faad2 through 2.10.0. A heap-buffer-overflow exists in the function lt_prediction located in lt_predict.c. It allows an attacker to cause code Execution. (CVE-2021-32278)

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

Solution
