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, remote attackers could cause a denial of service (application crash).

CVE-2017-7611

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

CVE-2017-7610

By using a crafted ELF file 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.
