Last modified: 2017-07-14 14:38:11 UTC
Ref: http://seclists.org/oss-sec/2017/q1/506 ============================================= Description: audiofile is a C-based library for reading and writing audio files in many common formats. A fuzz with a wav file as input produced an heap overflow.

I discovered multiple crashes in the audiofile library. The maintainer was informed privately, I didn't see reactions and all details are public on my blog. I posted them to the cveform too, but I didn't get response. I'll send update if something will change. -- Agostino Sarubbo Gentoo Linux Developer ========================================================
