"Several issues in elfutils, a collection of utilities to handle ELF
objects, have been found either by fuzzing or by using an
AddressSanitizer.

CVE-2019-7665 Due to a heap-buffer-overflow problem in function
elf32_xlatetom() a crafted ELF input can cause segmentation faults.

CVE-2019-7150 Add sanity check for partial core file dynamic data
read.

CVE-2019-7149 Due to a heap-buffer-overflow problem in function
read_srclines() a crafted ELF input can cause segmentation faults.

CVE-2018-18521 By using a crafted ELF file, containing a zero
sh_entsize, a divide-by-zero vulnerability could allow remote
attackers to cause a denial of service (application crash).

CVE-2018-18520 By fuzzing an Invalid Address Deference problem in
function elf_end has been found.

CVE-2018-18310 By fuzzing an Invalid Address Read problem in eu-stack
has been found.

CVE-2018-16062 By using an AddressSanitizer a heap-buffer-overflow has
been found.

CVE-2017-7613 By using fuzzing it was found that an allocation failure
was not handled properly.

CVE-2017-7612 By using a crafted ELF file, containing an invalid
sh_entsize, a remote attackers could cause a denial of service
(application crash).

CVE-2017-7611 By using a crafted ELF file a remote attackers could
cause a denial of service (application crash).

CVE-2017-7610 By using a crafted ELF file a remote attackers could
cause a denial of service (application crash).

CVE-2017-7608 By fuzzing a heap based buffer overflow has been
detected.

For Debian 8 'Jessie', these problems have been fixed in version
0.159-4.2+deb8u1.

We recommend that you upgrade your elfutils packages.
