elfutils v0.189 was discovered to contain a NULL pointer dereference via the handleverdef() function at readelf.c.

Elfutils is vulnerable to a heap-based buffer over-read in the libdw/dwarfgetaranges.c:dwarfgetaranges() function. An attacker could exploit this to cause a crash in the eu-addr2line command via a crafted file.

Elfutils through version 0.173 is vulnerable to a heap-based buffer over-read due to incorrect checks for the end of attribute lists in the libdw/dwarfgetabbrev.c:libdwgetabbrev() and libdw/dwarfhasattr.c:dwarfhasattr() functions. An attacker could exploit this to cause a crash via a crafted ELF.

Elfutils through version 0.173 is vulnerable to a double-free in the libelf/elfend.c:elfend() function due to the decompression of section data multiple times.. An attacker could exploit this to cause a crash or possibly have unspecified other impact via a crafted ELF.

In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32xlatetom in elf32xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because eblcorenote does not reject malformed core file notes.

In elfutils 0.175, there is a buffer over-read in the eblobjectnote function in eblobjnote.c in libebl. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted elf file.

A flaw was found in elfutils 0.174. A Divide-by-zero vulnerabilities in the function arlibaddsymbols() in arlib.c allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero shentsize is mishandled.

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