Gentoo Linux Security Advisory
Title: OpenSSL: Denial of service (GLSA 202012-13)
Severity: low
Exploitable: local, remote
Date: 2020-12-23
Bug(s): #759079
ID: 202012-13
Synopsis
A vulnerability in OpenSSL might allow remote attackers to cause a
Denial of Service condition.
Background
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
(SSL v2/v3) and Transport Layer Security (TLS v1/v1.1/v1.2/v1.3) as well
as a general purpose cryptography library.
Affected Packages
Package: dev-libs/openssl
Vulnerable: < 1.1.1i
Unaffected: >= 1.1.1i
Architectures: All supported architectures
Description
A null pointer dereference flaw was found in OpenSSL.
Impact
A remote attacker, able to control the arguments of the GENERAL_NAME_cmp
function in an application linked against OpenSSL, could possibly cause a
Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
All OpenSSL users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.1.1i"
|
