Doc Text:
A flaw was found in alsa-lib. This denial of service vulnerability exists in the multi PCM plugin due to a failure to validate sparse binding indices before array access. A local attacker can supply a malicious ALSA configuration file with sparse bindings. This can trigger an out-of-bounds array read and assertion failure, causing the application to terminate unexpectedly.
