Debian DLA-2802-1 : elfutils - LTS security update

critical Nessus Plugin ID 154749

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2802 advisory.

- dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file. (CVE-2018-16062)

- libelf/elf_end.c in elfutils 0.173 allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact because it tries to decompress twice.
(CVE-2018-16402)

- 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. (CVE-2018-18310)

- 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-2018-18520)

- 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-2018-18521)

- 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-2019-7150)

- 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-2019-7665)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the elfutils packages.

For Debian 9 stretch, these problems have been fixed in version 0.168-1+deb9u1.
