An update for golang is now available for HCE 2.0 Security Advisory hws_security@huawei.com Huawei Cloud HCE2-SA-2023-0284 Final 1.0 1.0 2023-09-15T08:04:42:00Z current version 2023-09-15T08:04:42:00Z 2023-09-15T08:04:42:00Z HCE SA Engine 1.0.0 An update for golang is now available for HCE 2.0 HCE Security has rated this update as having a security impact of Moderate.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section. Security Fix(es): Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable.
