CVE-2018-20194 (GCVE-0-2018-20194)

Vulnerability from cvelistv5 – Published: 2018-12-18 01:00 – Updated: 2024-08-05 11:58

Summary

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.
