Information leak in do_sigaltstack Restore missing LIRC drivers, dropped in previous release. Backport upstream fixes that further improve the security of mmap of low addresses. (CVE-2009-2695)
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
