Description

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or information leaks.

  • CVE-2013-6885 It was discovered that under specific circumstances, a combination of write operations to write-combined memory and locked CPU instructions may cause a core hang on AMD 16h 00h through 0Fh processors. A local user can use this flaw to mount a denial of service (system hang) via a crafted application.

For more information please refer to the AMD CPU erratum 793 in http://support.amd.com/TechDocs/51810_16h_00h-0Fh_Rev_Guide.pdf

  • CVE-2014-8133 It was found that the espfix funcionality can be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks for) and using it for stack. A local unprivileged user could potentially use this flaw to leak kernel stack addresses and thus allowing to bypass the ASLR protection mechanism.

  • CVE-2014-9419 It was found that on Linux kernels compiled with the 32 bit interfaces (CONFIG_X86_32) a malicious user program can do a partial ASLR bypass through TLS base addresses leak when attacking other programs.

  • CVE-2014-9529 It was discovered that the Linux kernel is affected by a race condition flaw when doing key garbage collection, allowing local users to cause a denial of service (memory corruption or panic).

  • CVE-2014-9584 It was found that the Linux kernel does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image.
