Discussion

Advanced Linux Sound Architecture Library Stack Protection Disabling Weakness

The Advanced Linux Sound Architecture (ALSA) library contains a weakness that disables stack protection schemes for its children.

If a child application of the ALSA library contains an exploitable stack overflow, it will not be protected against by any stack protection schemes that may be in place, potentially allowing arbitrary code to be executed on the computer.
