crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

CVE-2023-54365

The CVE covers Traefik versions prior to 2.10.5 and 3.0.0-beta4 affected by a denial-of-service in HTTP/2 request handling derived from the Go standard library’s HTTP/2 implementation (the Rapid Reset technique). A remote attacker can rapidly create and cancel HTTP/2 streams, exhausting server re...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

Oracle Linux 9 : buildah (ELSA-2026-19186)

The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2026-19186 advisory. - fixes CVE-2026-34986 - Rebuild for new golang to address CVE-2025-61726 Tenable has extracted the preceding description block directly from the Oracle Linux...

The vulnerability of the Go language-based HTTP/2 protocol implementation allows a attacker to cause a service failure.

The vulnerability in the HTTP/2 implementation using the Go programming language arises from executing a loop with an unreachable exit condition when processing the value of SETTINGSMAXFRAMESIZE, which is equal to 0. Exploiting this vulnerability could allow a remote attacker to cause a service...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

crypto/x509: golang: Denial of Service due to excessive resource consumption via crafted certificate

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the HostnameError.Error function. This flaw, caused by unbounded string concatenation, leads to excessive resource...

golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...
