alsa-lib — security advisory
alsa-lib through 1.2.16.1 contains a denial of service vulnerability in the multi PCM plugin that fails to validate sparse binding indices before array access. Attackers can supply a malicious ALSA configuration file with sparse bindings to trigger an out-of-bounds array read and assertion failure, causing the application to abort.
