Synopsis
========
A vulnerability has been discovered in Orc, which can lead to arbitrary
code execution
Background
==========
Orc is a library and set of tools for compiling and executing
very simple programs that operate on arrays of data. The "language"
is a generic assembly language that represents many of the features
available in SIMD architectures, including saturated addition and
subtraction, and many arithmetic operations.
Affected packages
=================
Package Vulnerable Unaffected
------------ ------------ ------------
dev-lang/orc < 0.4.40 >= 0.4.40
Description
===========
Please review the CVE identifier referenced below for details.
Impact
======
It is possible for a malicious third party to trigger a buffer overflow
and effect code execution with the same privileges as the orc compiler
is called with by feeding it with malformed orc source files.
This only affects developers and CI environments using orcc, not users
of liborc.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Orc users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/orc-0.4.40"
