Descriptions
The d_walk function in fs/dcache.c in the Linux kernel through 3.17.2 does not properly maintain the semantics of rename_lock, which allows local users to cause a denial of service (deadlock and system hang) via a crafted application.
La función d_walk en fs/dcache.c en el kernel de Linux hasta 3.17.2 no mantiene debidamente la semántica de rename_lock, lo que permite a usuarios locales causar una denegación de servicio (bloqueo y cuelgue del sistema) a través de una aplicación manipulada.
A flaw was found in the way the Linux kernel's VFS subsystem handled file system locks. A local, unprivileged user could use this flaw to trigger a deadlock in the kernel, causing a denial of service on the system.
A flaw was discovered in the Kernel Virtual Machine's (KVM) emulation of the SYSTENTER instruction when the guest OS does not initialize the SYSENTER MSRs. A guest OS user could exploit this flaw to cause a denial of service of the guest OS (crash) or potentially gain privileges on the guest OS. Andy Lutomirski discovered an information leak in the Linux kernel's Thread Local Storage (TLS) implementation allowing users to bypass the espfix to obtain information that could be used to bypass the Address Space Layout Randomization (ASLR) protection mechanism. A local user could exploit this flaw to obtain potentially sensitive information from kernel memory. Various other issues were also addressed.
