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"
References
==========
