Problem description: The alsa-lib package provides a library of functions for communication with kernel sound drivers. A flaw in the alsa mixer code was discovered that caused stack execution protection to be disabled for the libasound.so library. The effect of this flaw is that stack execution protection, through NX or Exec-Shield, would be disabled for any application linked to libasound. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0087 to this issue Users are advised to upgrade to this updated package, which contains a patched version of the library which correctly enables stack execution protection. 4.
