CVE-2017-9055

An issue, also known as DW201703-001, was discovered in libdwarf 2017-03-21. In dwarf_formsdata() a few data types were not checked for being in bounds, leading to a heap-based buffer over-read.

CVE-2017-9054

An issue, also known as DW201703-002, was discovered in libdwarf 2017-03-21. In _dwarf_decode_s_leb128_chk() a byte pointer was dereferenced just before it was checked for being in bounds, leading to a heap-based buffer over-read.

CVE-2017-9053

An issue, also known as DW201703-005, was discovered in libdwarf 2017-03-21. A heap-based buffer over-read in _dwarf_read_loc_expr_op() is due to a failure to check a pointer for being in bounds (in a few places in this function).

CVE-2017-9052

An issue, also known as DW201703-006, was discovered in libdwarf 2017-03-21. A heap-based buffer over-read in dwarf_formsdata() is due to a failure to check a pointer for being in bounds (in a few places in this function) and a failure in a check in dwarf_attr_list().

CVE-2016-5041

dwarf_macro5.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (NULL pointer dereference) via a debugging information entry using DWARF5 and without a DW_AT_name.

CVE-2016-9276

The dwarf_get_aranges_list function in dwarf_arrange.c in Libdwarf before 20161124 allows remote attackers to cause a denial of service (out-of-bounds read).

CVE-2016-9558

(1) libdwarf/dwarf_leb.c and (2) dwarfdump/print_frames.c in libdwarf before 20161124 allow remote attackers to have unspecified impact via a crafted bit pattern in a signed leb number, aka a "negation overflow."

CVE-2016-5027

dwarf_form.c in libdwarf 20160115 allows remote attackers to cause a denial of service (crash) via a crafted elf file.

CVE-2016-7511

Integer overflow in the dwarf_die_deliv.c in libdwarf 20160613 allows remote attackers to cause a denial of service (crash) via a crafted file.

• Update to 20120410-2+deb7u2build0.16.04.1

CVE-2016-7510

The read_line_table_program function in dwarf_line_table_reader_common.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read) via crafted input.

• Update to 20120410-2+deb7u2build0.16.04.1

CVE-2016-5044

The WRITE_UNALIGNED function in dwarf_elf_access.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds write and crash) via a crafted DWARF section.

CVE-2016-5043

The dwarf_dealloc function in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted DWARF section.

CVE-2016-5042

The dwarf_get_aranges_list function in libdwarf before 20160923 allows remote attackers to cause a denial of service (infinite loop and crash) via a crafted DWARF section.

• Update to 20120410-2+deb7u2build0.16.04.1

CVE-2016-5040

libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a large length value in a compilation unit header.

CVE-2016-5039
