USN-1941-1: Linux kernel vulnerabilities
First published: Fri Sep 06 2013(Updated: )
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)
