Synopsis
========
Multiple vulnerabilities have been found in Binutils, the worst of
which may allow remote attackers to cause a Denial of Service
condition.
Background
==========
The GNU Binutils are a collection of tools to create, modify and
analyse binary files. Many of the files use BFD, the Binary File
Descriptor library, to do low-level manipulation.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-devel/binutils < 2.32-r1 >= 2.32-r1
Description
===========
Multiple vulnerabilities have been discovered in Binutils. Please
review the referenced CVE identifiers for details.
Impact
======
A remote attacker, by enticing a user to compile/execute a specially
crafted ELF, object, PE, or binary file, could possibly cause a Denial
of Service condition or have other unspecified impacts.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Binutils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/binutils-2.32-r1"
