Detailed paths

  • Introduced through: centos:7.7.1908@* bind-license@32:9.11.4-9.P2.el7

Overview

Affected versions of this package are vulnerable to RHSA-2020:2344. The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly. Security Fix(es): * bind: BIND does not sufficiently limit the number of fetches performed when processing referrals (CVE-2020-8616) * bind: A logic error in code which checks TSIG validity can be used to trigger an assertion failure in tsig.c (CVE-2020-8617) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

  • Introduced through: krb5-libs@1.15.1-37.el7_6
  • Fixed in: 0:1.15.1-37.el7_7.2

Detailed paths

  • Introduced through: centos:7.7.1908@* krb5-libs@1.15.1-37.el7_6

Overview

Affected versions of this package are vulnerable to RHBA-2019:2599. Kerberos is a network authentication system, which can improve the security of your network by eliminating the insecure practice of sending passwords over the network in unencrypted form. It allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos key distribution center (KDC). This update fixes the following bug: * KDC and keytab can disagree on kvno after update (BZ#1732743)

Remediation

Upgrade krb5-libs to version or higher.
