Description
It was discovered that elfutils incorrectly handled certain malformed
files. If a user or automated system were tricked into processing a
specially crafted file, elfutils could be made to crash or consume
resources, resulting in a denial of service (CVE-2017-7607, CVE-2017-7608,
CVE-2017-7609, CVE-2017-7610, CVE-2017-7611, CVE-2017-7612, CVE-2017-7613,
CVE-2018-16062, CVE-2018-16402, CVE-2018-16403, CVE-2018-18310,
CVE-2018-18520, CVE-2018-18521, CVE-2019-7149, CVE-2019-7150,
CVE-2019-7665).
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) (CVE-2019-7664).
