Vulnerability from variot
A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches performed when processing referrals can, through the use of specially crafted referrals, cause a recursing server to issue a very large number of fetches in an attempt to process the referral. This has at least two potential effects: The performance of the recursing server can potentially be degraded by the additional work required to perform these fetches, and The attacker can exploit this behavior to use the recursing server as a reflector in a reflection attack with a high amplification factor. XACK DNS Is a corporation XACK Provides DNS Software for servers. XACK DNS In general NXNSAttack Service disruption due to a problem called (DoS) There are vulnerabilities that can be attacked. This vulnerability information is provided by the developer for the purpose of disseminating it to product users. IPA Report to JPCERT/CC Coordinated with the developer.The following service operation interruptions by a remote third party (DoS) You may be attacked. -Increases the load of the full resolver and reduces performance. ・ Abuse the full resolver as a stepping stone for reflection attacks. ISC (Internet Systems Consortium) Provides BIND There are multiple vulnerabilities in. * DNS Insufficient control of name resolution behavior - CVE-2020-8616 * tsig.c Assertion error occurs - CVE-2020-8617The expected impact depends on each vulnerability, but it may be affected as follows. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

- Description:
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.
- Solution:
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing the update, the BIND daemon (named) will be restarted automatically.

"data": "A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches performed when processing referrals can, through the use of specially crafted referrals, cause a recursing server to issue a very large number of fetches in an attempt to process the referral. This has at least two potential effects: The performance of the recursing server can potentially be degraded by the additional work required to perform these fetches, and The attacker can exploit this behavior to use the recursing server as a reflector in a reflection attack with a high amplification factor. XACK DNS Is a corporation XACK Provides DNS Software for servers. XACK DNS In general NXNSAttack Service disruption due to a problem called (DoS) There are vulnerabilities that can be attacked.

Summary:\n\nAn update for bind is now available for Red Hat Enterprise Linux 7.4\nAdvanced Update Support, Red Hat Enterprise Linux 7.4 Telco Extended Update\nSupport, and Red Hat Enterprise Linux 7.4 Update Services for SAP\nSolutions. \n\nRed Hat Product Security has rated this update as having a security impact\nof Important. A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available for each vulnerability\nfrom the CVE link(s) in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Server AUS (v. 7.4) - noarch, x86_64\nRed Hat Enterprise Linux Server E4S (v. 7.4) - noarch, ppc64le, x86_64\nRed Hat Enterprise Linux Server Optional AUS (v. 7.4) - x86_64\nRed Hat Enterprise Linux Server Optional E4S (v. 7.4) - ppc64le, x86_64\nRed Hat Enterprise Linux Server Optional TUS (v. 7.4) - x86_64\nRed Hat Enterprise Linux Server TUS (v. 7.4) - noarch, x86_64\n\n3. Description:\n\nThe Berkeley Internet Name Domain (BIND) is an implementation of the Domain\nName System (DNS) protocols. BIND includes a DNS server (named); a resolver\nlibrary (routines for applications to use when interfacing with DNS); and\ntools for verifying that the DNS server is operating correctly. \n\nSecurity Fix(es):\n\n* bind: BIND does not sufficiently limit the number of fetches performed\nwhen processing referrals (CVE-2020-8616)\n\n* bind: A logic error in code which checks TSIG validity can be used to\ntrigger an assertion failure in tsig.c (CVE-2020-8617)\n\nFor more details about the security issue(s), including the impact, a CVSS\nscore, acknowledgments, and other related information, refer to the CVE\npage(s) listed in the References section. \n\n4. Solution:\n\nFor details on how to apply this update, which includes the changes\ndescribed in this advisory, refer to:\n\nhttps://access.redhat.com/articles/11258\n\nAfter installing the update, the BIND daemon (named) will be restarted\nautomatically. \n\n5. Bugs fixed (https://bugzilla.redhat.com/):\n\n1836118 - CVE-2020-8616 bind: BIND does not sufficiently limit the number of fetches performed when processing referrals\n1836124 - CVE-2020-8617 bind: A logic error in code which checks TSIG validity can be used to trigger an assertion failure in tsig.c\n\n6.
