Affected Packages

------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/openssl < 1.0.0e >= 1.0.0e

Impact

===== A context-dependent attacker could cause a Denial of Service, possibly execute arbitrary code, bypass intended key requirements, force the downgrade to unintended ciphers, bypass the need for knowledge of shared secrets and successfully authenticate, bypass CRL validation, or obtain sensitive information in applications that use OpenSSL.

Workaround

There is no known workaround at this time.
