patch. A local user could use this flaw to cause a denial of service
(memory exhaustion). (CVE-2007-5494, Important)

several wireless LAN modules. In certain circumstances, a remote
attacker could trigger this flaw by sending a malicious packet over a
wireless network and cause a denial of service (kernel crash).
A flaw was found in the Advanced Linux Sound Architecture (ALSA). A
local user who had the ability to read the /proc/driver/snd-page-alloc
file could see portions of kernel memory. (CVE-2007-4571, Moderate).
In addition to the security issues described above, several bug fixes
preventing possible memory corruption, system crashes, SCSI I/O fails,
networking drivers performance regression and journaling block device
layer issue were also included.
