CVE-2018-8970 SUSE CVE security@suse.de SUSE Security Team SUSE CVE-2018-8970 Interim 1 9 2023-12-09T00:51:13Z current 2021-05-30T14:12:06Z 2023-12-09T00:51:13Z cve-database/bin/generate-cvrf-cve.pl 2020-12-27T01:00:00Z CVE-2018-8970 The int_x509_param_set_hosts function in lib/libcrypto/x509/x509_vpm.c in LibreSSL 2.7.0 before 2.7.1 does not support a certain special case of a zero name length, which causes silent omission of hostname verification, and consequently allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate. NOTE: the LibreSSL documentation indicates that this special case is supported, but the BoringSSL documentation does not.
