Date:	05/12/2008
Bugs:	#198979
ID:	200805-11

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	Architecture(s)
dev-scheme/chicken	< 3.1.0	>= 3.1.0	All supported architectures

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
    # emerge --ask --oneshot --verbose ">=dev-scheme/chicken-3.1.0"
