bugzilla: 51868
CVE: NA

--------------------------------

[ Upstream commit 84168d1b ]

The code validates that segments of p_memsz bytes of a segment will fit
in the provided memory region, but does not validate that p_filesz bytes
will, which means that an incorrectly crafted ELF header might write
beyond the provided memory region.
