Synopsis

========

 

An untrusted search path vulnerability in Valgrind might result in the

execution of arbitrary code.

 

Background

==========

 

Valgrind is an open-source memory debugger.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 dev-util/valgrind < 3.4.0 >= 3.4.0

 

Description

===========

 

Tavis Ormandy reported that Valgrind loads a .valgrindrc file in the

current working directory, executing commands specified there.

 

Impact

======

 

A local attacker could prepare a specially crafted .valgrindrc file and

entice a user to run Valgrind from the directory containing that file,

resulting in the execution of arbitrary code with the privileges of the

user running Valgrind.

 

Workaround

==========

 

Do not run "valgrind" from untrusted working directories.

 

Resolution

==========

 

All Valgrind users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=dev-util/valgrind-3.4.0"
