Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS

Summary:

elfutils could be made to overwrite files in the root directory if it received a specially crafted file.

Software Description: - elfutils: collection of utilities to handle ELF objects

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10:
libelf1 0.160-0ubuntu2.1

Ubuntu 14.04 LTS:
libelf1 0.158-0ubuntu5.2

Ubuntu 12.04 LTS:
libelf1 0.152-1ubuntu3.1

Ubuntu 10.04 LTS:
libelf1 0.143-1ubuntu0.1

After a standard system update you need to restart applications using libelf1 to make all the necessary changes.
