Arch Linux Security Advisory ASA-201612-4 ========================================= Severity: High Date : 2016-12-03 CVE-ID : CVE-2016-5027 CVE-2016-5028 CVE-2016-5029 CVE-2016-5030 CVE-2016-5031 CVE-2016-5032 CVE-2016-5033 CVE-2016-5035 CVE-2016-5037 CVE-2016-5040 CVE-2016-5041 CVE-2016-5043 CVE-2016-5044 CVE-2016-7510 CVE-2016-7511 CVE-2016-8679 CVE-2016-8680 CVE-2016-8681 CVE-2016-9275 CVE-2016-9276 CVE-2016-9480 CVE-2016-9558 Package : libdwarf Type : multiple issues Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package libdwarf before version 20161124-1 is vulnerable to multiple issues including arbitrary code execution, information disclosure and denial of service. Resolution ========== Upgrade to 20161124-1. # pacman -Syu "libdwarf>=20161124-1" The problems have been fixed upstream in version 20161124. Workaround ========== None. Description =========== - CVE-2016-5027 (denial of service) A vulnerability was found in libdwarf. A malicious object with data all-bits-on could bypass length checks which results in an out-of- bounds read. - CVE-2016-5028 (denial of service) A null pointer dereference vulnerability was found in libdwarf. It exists due to a corrupted object file. Libdwarf was not dealing with empty (bss-like) sections since it really did not expect to see such in sections it reads. - CVE-2016-5029 (denial of service) A null pointer dereference vulnerability was found in libdwarf in create_fullest_file_path() function. This is due to corrupted dwarf and the fix detects this corruption and if that null string pointer happens undetected a static string is substituted so readers can notice the situation. - CVE-2016-5030 (denial of service) A null pointer dereference vulnerability was found in libdwarf in _dwarf_calculate_info_section_end_ptr() function. - CVE-2016-5031 (information disclosure) An out-of-bounds read vulnerability was found in libdwarf in print_frame_inst_bytes() function. - CVE-2016-5032 (information disclosure) An out-of-bounds read vulnerability was found in libdwarf in dwarf_get_xu_hash_entry() function. - CVE-2016-5033 (information disclosure) An out-of-bounds read vulnerability was found in libdwarf in print_exprloc_content. - CVE-2016-5035 (information disclosure) An out-of-bounds read vulnerability was found in dwarf_line_table_reader.c. - CVE-2016-5037 (denial of service) A null pointer dereference vulnerability was found in _dwarf_load_section. - CVE-2016-5040 (denial of service) A vulnerability was found in libdwarf. If the data read for a compilation unit header contains a too large length value the library will read outside of its bounds and crash the application. - CVE-2016-5041 (denial of service) A vulnerability was found in libdwarf. If no DW_AT_name is present in a debugging information entry using DWARF5 macros a null dereference in dwarf_macro5.c will crash the application. - CVE-2016-5043 (information disclosure) A vulnerability was found in libdwarf. A function dwarf_dealloc() did not check the Dwarf_Ptr space argument before using it which leads to an out-of-bounds read. - CVE-2016-5044 (arbitrary code execution) A vulnerability was found in libdwarf in dwarf_elf_access.c:1071. A crafted ELF file may lead to a large offset value, which bigger than the size of target_section heap chunk, then this WRITE_UNALIGNED() function will write the value of &outval out of the heap chunk. The offset is a 64bit unsigned int value, so this is more than a heap overflow bug, but also a out-of-bound write bug. - CVE-2016-7510 (information disclosure) An out-of-bounds read vulnerability was found in read_line_table_program() in libdwarf. - CVE-2016-7511 (denial of service) An integer overflow vulnerability was found in dwarf_die_deliv.c causing segmentation fault. - CVE-2016-8679 (information disclosure) An out of bounds heap read vulnerability was found in _dwarf_get_size_of_val triggered by invoking dwarfdump command on crafted file. - CVE-2016-8680 (information disclosure) An out of bounds heap read vulnerability was found in _dwarf_get_abbrev_for_code triggered by invoking dwarfdump command on crafted file. - CVE-2016-8681 (information disclosure) An out of bounds heap read vulnerability was found in _dwarf_get_abbrev_for_code triggered by invoking dwarfdump command on crafted file. - CVE-2016-9275 (information disclosure) An out of bounds heap read was found in _dwarf_skim_forms in dwarf_macro5.c triggered by crafted input to dwarfdump utility. - CVE-2016-9276 (information disclosure) An out of bounds heap read was found in dwarf_get_aranges_list in dwarf_arrange.c triggered by crafted input to dwarfdump utility. - CVE-2016-9480 (information disclosure) libdwarf allows context-dependent attackers to obtain sensitive information or cause a denial of service by using the "malformed dwarf file" approach, related to a "Heap Buffer Over-read" issue affecting the dwarf_util.c component. - CVE-2016-9558 (denial of service) A negation overflow vulnerability was found in dwarf_leb.c triggered by crafted input to dwarfdump utility. Impact ====== An attacker could obtain sensitive information, execute arbitrary code or crash the application.
