Chicken: Multiple vulnerabilities — GLSA 200805-11

Multiple vulnerabilities in Chicken could result in the execution of arbitrary code.

Affected Packages

dev-scheme/chicken on all architectures
Affected versions < 3.1.0
Unaffected versions >= 3.1.0

Background

Chicken is a Scheme interpreter and native Scheme to C compiler.

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"
