Synopsis ========
Multiple vulnerabilities have been found in OpenSSL, the worst of which allows attackers to conduct a time based side-channel attack.
Background ==========
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general purpose cryptography library.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/openssl < 1.0.2j >= 1.0.2j
Description ===========
Multiple vulnerabilities have been discovered in OpenSSL. Please review the CVE identifiers and the International Association for Cryptologic Research's (IACR) paper, "Make Sure DSA Signing Exponentiations Really are Constant-Time" for further details.
Impact ======
Remote attackers could cause a Denial of Service condition or have other unspecified impacts. Additionally, a time based side-channel attack may allow a local attacker to recover a private DSA key.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.2j"
