Security update for grafana

This update for grafana fixes the following issues:

  • CVE-2023-29409: Restrict RSA keys in certificates to less than or equal to 8192 bits to avoid DoSing client/server while validating signatures for extremely large RSA keys. (bsc#1213880) There are no direct source changes. The CVE is fixed rebuilding the sources with the patched Go version.

Описание

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.
