Ubuntu Security Notice 1913-1 - Jonathan Salwan discovered an information leak in the Linux kernel's cdrom driver. A local user can exploit this leak to obtain sensitive information from kernel memory if the CD-ROM drive is malfunctioning. A flaw was discovered in the Linux kernel when an IPv6 socket is used to connect to an IPv4 destination. An unprivileged local user could exploit this flaw to cause a denial of service (system crash). An information leak was discovered in the IPSec key_socket implementation in the Linux kernel. An local user could exploit this flaw to examine potentially sensitive information in kernel memory. Various other issues were also addressed.
