Test ID:	1.3.6.1.4.1.25623.1.1.2.2023.2896
Category:	Huawei EulerOS Local Security Checks
Title:	Huawei EulerOS: Security Advisory for golang (EulerOS-SA-2023-2896)
Summary:	The remote host is missing an update for the Huawei EulerOS 'golang' package(s) announced via the EulerOS-SA-2023-2896 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'golang' package(s) announced via the EulerOS-SA-2023-2896 advisory. Vulnerability Insight: 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.(CVE-2023-29409) Affected Software/OS: 'golang' package(s) on Huawei EulerOS V2.0SP9(x86_64). Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
