Mandriva Linux Security Advisory 2015-104

Mandriva Linux Security Advisory 2015-104
Posted Mar 30, 2015
Authored by Mandriva | Site mandriva.com

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.

Package : elfutils
Date : March 29, 2015
Affected: Business Server 2.0
_______________________________________________________________________

Problem Description:

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).
