CVE-2014-0172

Status Candidate

Overview

Integer overflow in the check_section function in dwarf_begin_elf.c in the libdw library, as used in elfutils 0.153 and possibly through 0.158 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed compressed debug section in an ELF file, which triggers a heap-based buffer overflow.

Mandriva Linux Security Advisory 2015-104

Mandriva Linux Security Advisory 2015-104 - The libdw library provides support for accessing DWARF debugging information inside ELF files. An integer overflow flaw in check_section(), leading to a heap-based buffer overflow, was found in the libdw library. A malicious ELF file could cause an application using libdw to crash or, potentially, execute arbitrary code with the privileges of the user running the application. Directory traversal vulnerability in the read_long_names function in libelf/elf_begin.c in elfutils allows remote attackers to write to arbitrary files to the root directory via a / in a crafted archive, as demonstrated using the ar program.

Ubuntu Security Notice USN-2188-1
Posted May 1, 2014

Ubuntu Security Notice 2188-1 - Florian Weimer discovered that the elfutils libdw library incorrectly handled malformed compressed debug sections in ELF files. If a user or automated system were tricked into processing a specially crafted ELF file, applications linked against libdw could be made to crash, or possibly execute arbitrary code.
