Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU38974
Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2017-9053
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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-ID: CVE-2017-9054
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.

DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
