Affected Packages

------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/openssl < 1.0.1h-r1 *>= 0.9.8z_p5 *>= 0.9.8z_p4 *>= 0.9.8z_p1 *>= 0.9.8z_p3 *>= 0.9.8z_p2 *>= 1.0.0m >= 1.0.1h-r1

Impact

===== A remote attacker could send specially crafted DTLS fragments to an OpenSSL DTLS client or server to possibly execute arbitrary code with the privileges of the process using OpenSSL. Furthermore, an attacker could force the use of weak keying material in OpenSSL SSL/TLS clients and servers, inject data across sessions, or cause a Denial of Service via various vectors.

Workaround

There is no known workaround at this time.
