Synopsis
Multiple Information Disclosure vulnerabilities in OpenSSL allow attackers to obtain sensitive information.
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 < 1.0.2r >= 1.0.2r
Impact
=====
A remote attacker to obtain sensitive information, caused by the
failure to immediately close the TCP connection after the hosts
encounter a zero-length record with valid padding.
A local attacker could run a malicious process next to legitimate
processes using the architecture’s parallel thread running capabilities
to leak encrypted data from the CPU's internal processes.
Workaround
There is no known workaround at this time.
