CVE-2005-4900 (GCVE-0-2005-4900)

Vulnerability from cvelistv5

Published

2016-10-14 16:00

Modified

2024-08-08 00:01

Severity ?

CWE

Summary

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.
