This issue was patched in ALAS2-2019-1337.

NVD Description

Note: Versions mentioned in the description apply only to the upstream elfutils-libelf package and not the elfutils-libelf package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

In elfutils 0.175, a negative-sized memcpy is attempted in elf_cvt_note in libelf/note_xlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).
