Gentoo Linux Security Advisory

Title: OpenSSL: Multiple vulnerabilities (GLSA 201903-10)
Severity: normal
Exploitable: local, remote
Date: 2019-03-14
Bug(s): #673056, #678564
ID: 201903-10

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: dev-libs/openssl
Vulnerable: < 1.0.2r
Unaffected: >= 1.0.2r
Architectures: All supported architectures


Description

Multiple vulnerabilities have been discovered in OpenSSL. Please review
the CVE identifiers referenced below for details.


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.

Resolution

All OpenSSL users should upgrade to the latest version:
