=========================================
Severity: Medium
Date    : 2014-11-19
CVE-ID  : CVE-2014-8484 CVE-2014-8485 CVE-2014-8501 CVE-2014-8502
          CVE-2014-8503 CVE-2014-8504 CVE-2014-8737 CVE-2014-8738
Package : avr-binutils
Type    : multiple issues
Remote  : No
Link    : https://wiki.archlinux.org/title/CVE-2014

Summary
======
The package avr-binutils before version 2.24-3 is vulnerable to multiple
issues including but not limited to denial of service, directory
traversal, heap and stack overflow leading to possible code execution.

Resolution
=========
Upgrade to 2.24-3.

# pacman -Syu "avr-binutils>=2.24-3"

The problems have been fixed upstream but no release is available yet.

Workaround
=========
None.

Description
==========
- CVE-2014-8484 (invalid read)
Invalid read flaw leads to denial of service while parsing specially
crafted files in programs using libbfd.

- CVE-2014-8485 (out-of-bounds write)
Lack of range checking leading to controlled write in
_bfd_elf_setup_sections() which results in denial of service or possible
code execution in programs using libbfd.

- CVE-2014-8501 (out-of-bounds write)
Out-of-bounds write when parsing specially crafted PE executable leads
to denial of service in "strings", "nm" and "objdump".

- CVE-2014-8502 (heap overflow)
Heap buffer overflow when parsing specially crafted PE executable leads
to denial of service in "objdump".

- CVE-2014-8503 (stack overflow)
Stack overflow in "objdump" when parsing specially crafted ihex files
leads to denial of service or code execution.

- CVE-2014-8504 (stack overflow)
Stack overflow in the SREC parser leads to denial of service or code
execution when parsing specially crafted files.

- CVE-2014-8737 (directory traversal)
Directory traversal vulnerability allowing arbitrary file deletion and
creation.

- CVE-2014-8738 (out-of-bounds write)
Out-of-bounds memory write while processing a crafted "ar" archive leads
to denial of service in "objdump".

Impact
=====
An attacker with specially crafted files can perform denial of service,
directory traversal, heap and stack overflow leading to possible code
execution. Programs using libbfd may also be remotely exploitable.
