"An updated alsa-lib package that fixes a flaw that disabled stack
execution protection is now available for Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the
Red Hat Security Response Team.
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 CVE-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."
