Description Mark J. Cox (Product Security) 2007-09-13 04:32:05 EDT
iDefense reported a flaw in ALSA snd_mem_proc_read.  A local user who has the
ability to read the /proc/driver/snd-page-alloc file could potentially gain
access to read sensitive information from kernel memory.

CVSS v2 Base score: 2.1  (Low) (AV:L/AC:L/Au:N/C:P/I:N/A:N)


Red Hat would like to credit iDefense and Neil Kettle for reporting this issue.

Comment 5 Mark J. Cox (Product Security) 2007-09-14 05:06:25 EDT
Exploiting this issue will give the user the ability to see a number of
uninitialized bytes, up to 41 bytes, but they have no control over what they see.
