Synopsis
========
Multiple vulnerabilities in Chicken could result in the execution of
arbitrary code.
Background
==========
Chicken is a Scheme interpreter and native Scheme to C compiler.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-scheme/chicken < 3.1.0 >= 3.1.0
Description
===========
Chicken includes a copy of PCRE which is vulnerable to multiple buffer
overflows and memory corruption vulnerabilities (GLSA 200711-30).
Impact
======
An attacker could entice a user to process specially crafted regular
expressions with Chicken, which could possibly lead to the execution of
arbitrary code, a Denial of Service or the disclosure of sensitive
information.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Chicken users should upgrade to the latest version:
# emerge --sync
