USN-3670-1: elfutils vulnerabilities

Releases

• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• elfutils - collection of utilities to handle ELF objects

Details

Agostino Sarubbo discovered that elfutils incorrectly handled certain
malformed ELF files. If a user or automated system were tricked into
processing a specially crafted ELF file, elfutils could be made to crash or
consume resources, resulting in a denial of service.

Update instructions

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

Ubuntu 16.04

• elfutils - 0.165-3ubuntu1.1
• libasm1 - 0.165-3ubuntu1.1
• libdw1 - 0.165-3ubuntu1.1
• libelf1 - 0.165-3ubuntu1.1

Ubuntu 14.04

• elfutils - 0.158-0ubuntu5.3
• libasm1 - 0.158-0ubuntu5.3
• libdw1 - 0.158-0ubuntu5.3
• libelf1 - 0.158-0ubuntu5.3

In general, a standard system update will make all the necessary changes.
