CVSS: 8.1EPSS: 3%CPEs: 25EXPL: 0CVE-2020-8625 – A vulnerability in BIND's GSSAPI security policy negotiation can be targeted by a buffer overflow attack
https://notcve.org/view.php?id=CVE-2020-8625
17 Feb 2021 — BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-ser... • http://www.openwall.com/lists/oss-security/2021/02/19/1 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
