Directory traversal vulnerability in the read_long_names function in libelf/elf_begin.c in elfutils 0.152 and 0.161 allows remote attackers to write to arbitrary files to the root directory via a / (slash) in a crafted archive, as demonstrated using the ar program.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - elfutils: directory traversal in read_long_names() (CVE-2014-9447)

  - elfutils: eu-size cannot handle recursive ar files (CVE-2018-18520)

  - The allocate_elf function in common.h in elfutils before 0.168 allows remote attackers to cause a denial     of service (crash) via a crafted ELF file, which triggers a memory allocation failure. (CVE-2016-10254)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Updated elfutils packages fix security vulnerabilities :

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 (such as eu-readelf) to crash or, potentially, execute arbitrary code with the privileges of the user running the application (CVE-2014-0172).

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 / (slash) in a crafted archive, as demonstrated using the ar program (CVE-2014-9447).

elfutils has been updated to fix one security issue :

  - Directory traversal vulnerability in the read_long_names     function in libelf/elf_begin.c in elfutils 0.152 and     0.161 allowed remote attackers to write to arbitrary     files to the root directory via a / (slash) in a crafted     archive, as demonstrated using the ar program.
    (bnc#911662). (CVE-2014-9447)

elfutils was updated to fix a directory traversal vulnerability (bnc#911662 CVE-2014-9447)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2482-1 advisory.

    Alexander Cherepanov discovered that libelf1 incorrectly handled certain filesystem paths while extracting     ar archives. An attacker could use this flaw to perform a directory traversal attack on the root directory     if the process extracting the ar archive has write access to the root directory.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Update to elfutils 0.161. Security fix for CVE-2014-9447.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
