Description

Mathias Krause discovered an information leak in the Linux kernel’s getsockname implementation for Logical Link Layer (llc) sockets. A local user could exploit this flaw to examine some of the kernel’s stack memory. (CVE-2012-6542)

Mathias Krause discovered information leaks in the Linux kernel’s Bluetooth Logical Link Control and Adaptation Protocol (L2CAP) implementation. A local user could exploit these flaws to examine some of the kernel’s stack memory. (CVE-2012-6544)

Mathias Krause discovered information leaks in the Linux kernel’s Bluetooth RFCOMM protocol implementation. A local user could exploit these flaws to examine parts of kernel memory. (CVE-2012-6545)

Mathias Krause discovered information leaks in the Linux kernel’s Asynchronous Transfer Mode (ATM) networking stack. A local user could exploit these flaws to examine some parts of kernel memory. (CVE-2012-6546)

Mathias Krause discovered an information leak in the Linux kernel’s UDF file system implementation. A local user could exploit this flaw to examine some of the kernel’s heap memory. (CVE-2012-6548)

Andrew Jones discovered a flaw with the xen_iret function in Linux kernel’s Xen virtualizeation. In the 32-bit Xen paravirt platform an unprivileged guest OS user could exploit this flaw to cause a denial of service (crash the system) or gain guest OS privilege. (CVE-2013-0228)

An information leak was discovered in the Linux kernel’s Bluetooth stack when HIDP (Human Interface Device Protocol) support is enabled. A local unprivileged user could exploit this flaw to cause an information leak from the kernel. (CVE-2013-0349)

A flaw was discovered in the Edgeort USB serial converter driver when the device is disconnected while it is in use. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1774)

Andrew Honig discovered a flaw in guest OS time updates in the Linux kernel’s KVM (Kernel-based Virtual Machine). A privileged guest user could exploit this flaw to cause a denial of service (crash host system) or potential escalate privilege to the host kernel level. (CVE-2013-1796)
