CVE-2019-7665

CWE-119
 
 
In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes.

 
 
CVE-2019-7664

CWE-119
 
 
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-2019-7150

CWE-125
 
 
An issue was discovered in elfutils 0.175. A segmentation fault can occur in the function elf64_xlatetom in libelf/elf32_xlatetom.c, due to dwfl_segment_report_module not checking whether the dyn data read from a core file is truncated. A crafted input can cause a program crash, leading to denial-of-service, as demonstrated by eu-stack.

 
 
CVE-2019-7149

CWE-125
 
 
A heap-based buffer over-read was discovered in the function read_srclines in dwarf_getsrclines.c in libdw in elfutils 0.175. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by eu-nm.

 
 
CVE-2019-7148

CWE-119
 
 
**DISPUTED** An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is not a real issue, but instead a "warning caused by ASAN because the allocation is big. By setting ASAN_OPTIONS=allocator_may_return_null=1 and running the reproducer, nothing happens."

 
 
CVE-2019-7146

CWE-119
 
 
In elfutils 0.175, there is a buffer over-read in the ebl_object_note function in eblobjnote.c in libebl. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted elf file, as demonstrated by eu-readelf.

CVE-2018-18521

CWE-369
 
 
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.

 
 
CVE-2018-18520

CWE-119
 
 
An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.

CVE-2018-18310

CWE-119
 
 
An invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl in elfutils through v0.174. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by consider_notes.

 
2018-09-03
 
CVE-2018-16403

CWE-125
 
 
libdw in elfutils 0.173 checks the end of the attributes list incorrectly in dwarf_getabbrev in dwarf_getabbrev.c and dwarf_hasattr in dwarf_hasattr.c, leading to a heap-based buffer over-read and an application crash.
