Multiple vulnerabilities in Chicken could result in the execution of arbitrary code.
| Package | dev-scheme/chicken on all architectures |
|---|---|
| Affected versions | < 3.1.0 |
| Unaffected versions | >= 3.1.0 |
Chicken is a Scheme interpreter and native Scheme to C compiler.
Chicken includes a copy of PCRE which is vulnerable to multiple buffer overflows and memory corruption vulnerabilities (GLSA 200711-30).
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.
There is no known workaround at this time.
All Chicken users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-scheme/chicken-3.1.0"
