Descriptions
An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be "jumped" over (the stack guard page is bypassed), this affects Linux Kernel versions 4.11.5 and earlier (the stackguard page was introduced in 2010).
Se ha descubierto un problema en el tamaño de la página de stack guard en Linux; específicamente, una página 4k stack guard no es lo suficientemente grande y puede "saltarse" (se omite la página de stack guard). Esto afecta al kernel de Linux en versiones 4.11.5 y anteriores (la página stackguard fue introducida en 2010).
A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap (or different memory region) and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is a kernel-side mitigation which increases the stack guard gap size from one page to 1 MiB to make successful exploitation of this issue more difficult.
