EUVD-2026-31396

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...

Astra Linux - уязвимость в golang-1.19

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...

Important: ecs-init

Issue Overview: The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value...

CVE-2023-39533

A flaw was found in the go-libp2p package. A malicious peer can use large RSA keys to run a resource exhaustion attack and force a node to spend time doing signature verification of the large key. This issue is present in the core/crypto module of go-libp2p and can occur during the Noise handshak...

AZL-37422 CVE-2023-39533 affecting package golang for versions less than 1.21.6-1

go-libp2p is the Go implementation of the libp2p Networking Stack. Prior to versions 0.27.8, 0.28.2, and 0.29.1 malicious peer can use large RSA keys to run a resource exhaustion attack & force a node to spend time doing signature verification of the large key. This vulnerability is present in th...

PT-2023-27004 · Go-Libp2P · Go-Libp2P

Name of the Vulnerable Software and Affected Versions: go-libp2p versions prior to 0.27.8 go-libp2p versions prior to 0.28.2 go-libp2p versions prior to 0.29.1 Description: A malicious peer can use large RSA keys to run a resource exhaustion attack and force a node to spend time doing signature...

Denial Of Service (DoS)

github.com/golang/go is vulnerable to Denial Of Service DoS. The vulnerability exists because handshakeclient.go does not set a max RSA key size, which can lead to extremely large RSA keys in certificate chains causing a client to expend significant CPU time to verify signatures. The fix sets the...
