Descriptions
The do_tkill function in kernel/signal.c in the Linux kernel before 3.8.9 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted application that makes a (1) tkill or (2) tgkill system call.
La función do_tkill en kernel/signal.c en el kernel de Linux anterior a v3.8.9 no inicializa cierta estructura de datos, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de aplicaciones manipuladas que realizan llamadas al sistema (1) tkill o (2) tgkill.
The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled sending of certain UDP packets over sockets that used the UDP_CORK option when the UDP Fragmentation Offload feature was enabled on the output device. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges on the system. A divide-by-zero flaw was found in the apic_get_tmcct() function in KVM's Local Advanced Programmable Interrupt Controller implementation. A privileged guest user could use this flaw to crash the host.
