USN-1912-1: Linux kernel vulnerabilities

Published Jul 29, 2013
·
Updated

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. (CVE-2013-2164) 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). (CVE-2013-2232) An information leak was discovered in the IPSec keysocket implementation in the Linux kernel. An local user could exploit this flaw to examine potentially sensitive information in kernel memory. (CVE-2013-2234) An information leak was discovered in the Linux kernel when reading broadcast messages from the notifypolicy interface of the IPSec keysocket. A local user could exploit this flaw to examine potentially sensitive information in kernel memory. (CVE-2013-2237) Kees Cook discovered a format string vulnerability in the Linux kernel's disk block layer. A local user with administrator privileges could exploit this flaw to gain kernel privileges. (CVE-2013-2851)
