Last modified Jun 17, 2026

CVE-2018-20197 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.32% chance of exploitation in the next 30 days.
