Chanam Park reported a NULL pointer flaw in the Linux kernel’s Ceph client. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1059)
Vasily Kulikov discovered a flaw in the Linux Kernel’s perf tool that allows for privilege escalation. A local user could exploit this flaw to run commands as root when using the perf tool. (CVE-2013-1060)
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 key_socket implementation in the Linux kernel. An local user could exploit this flaw to examine potentially sensitive information in kernel memory.
(CVE-2013-2234)
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)
Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the Linux kernel’s IPv6 stack. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-4162)
Hannes Frederic Sowa discovered a flaw in the IPv6 subsystem of the Linux kernel when the IPV6_MTU setsockopt option has been specified in combination with the UDP_CORK option. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-4163).
