CVE-2005-4900 Information

Description

SHA-1 is not collision resistant which makes it easier for context-dependent attackers to conduct spoofing attacks as demonstrated by attacks on the use of SHA-1 in TLS 1.2. NOTE: this CVE exists to provide a common identifier for referencing this SHA-1 issue; the existence of an identifier is not by itself a technology recommendation.
