Description:
The __clear_user function in arch/arm64/lib/clear_user.S in the Linux
kernel before 3.17.4 on the ARM64 platform allows local users to cause a
denial of service (system crash) by reading one byte beyond a /dev/zero
page boundary.
Ubuntu-Description:
Miloš Prchlík reported a flaw in how the ARM64 platform handles a single
byte overflow in __clear_user. A local user could exploit this flaw to
cause a denial of service (system crash) by reading one byte beyond a
/dev/zero page boundary.
Notes:
jdstrand> android kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.04 preview kernels
jdstrand> linux-lts-saucy no longer receives official support
jdstrand> linux-lts-quantal no longer receives official support
