RHSA-2026:49765
Vulnerability from csaf_redhat - Published: 2026-08-03 18:05 - Updated: 2026-08-09 18:57A flaw was found in the `crypto/x509` package of `golang`. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name (SAN) entries. The certificate verification process, specifically the `VerifyHostname` function, incurs excessive computational overhead due to repeated string operations when processing these entries. This can lead to a significant performance degradation or unresponsiveness of systems validating such certificates.

A flaw was found in Envoy, an open source edge and service proxy. A remote attacker can exploit this vulnerability by sending a specially crafted Connect protocol request to a direct response route. This action causes the `envoy.filters.http.grpc_stats` filter to crash, leading to a denial of service (DoS) for the Envoy process. This can disrupt services relying on the proxy.

A flaw was found in Envoy. An unauthenticated attacker can exploit a null pointer dereference vulnerability in the router filter. This occurs when handling HTTP 303 (See Other) internal redirects for body-less non-GET/HEAD requests. By sending a POST, PUT, DELETE, or PATCH request without a body to a specially configured route, and if the upstream responds with HTTP 303, the Envoy process will crash. This leads to a complete denial of service, terminating all active connections.

A flaw was found in Envoy, an open-source edge and service proxy. A remote attacker could exploit this vulnerability by sending deeply nested JSON objects to the affected system. This could lead to a stack overflow during the destruction of JSON objects, resulting in a Denial of Service (DoS) for the Envoy proxy.

A flaw was found in Envoy, an open source edge and service proxy. A remote attacker can exploit this vulnerability by sending a specially crafted, highly compressed zstd payload to an Envoy proxy with zstd decompression enabled. This can lead to massive memory allocation, causing severe memory exhaustion and potentially resulting in an Out-Of-Memory (OOM) kill and Denial of Service (DoS) for the Envoy proxy.

A flaw was found in Envoy, an open-source edge and service proxy. An attacker can exploit a heap write overflow vulnerability in Envoy's TCP StatsD sink by sending exceptionally long statistic names, such as those found in HTTP or gRPC request paths. This can lead to a denial-of-service, causing the process to crash, and potentially enable remote code execution.

Workaround

A flaw was found in Envoy, an open source edge and service proxy. This vulnerability occurs when Envoy translates an HTTP/3 request that is complete at the transport layer but still carries a nonzero Content-Length into an HTTP/1 request for an upstream server. If the upstream server responds before fully reading the declared body, a subsequent Envoy-generated request can be misinterpreted as part of the previous one. This can lead to a request desynchronization, allowing an attacker to bypass security policies and access unauthorized resources.

"text": "A flaw was found in the `crypto/x509` package of `golang`. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name (SAN) entries. The certificate verification process, specifically the `VerifyHostname` function, incurs excessive computational overhead due to repeated string operations when processing these entries. This can lead to a significant performance degradation or unresponsiveness of systems validating such certificates.",

"text": "A flaw was found in the Go standard library crypto/x509 package. When verifying a TLS certificate hostname, VerifyHostname processed each DNS Subject Alternative Name (SAN) entry in a loop and repeatedly split the candidate hostname on \".\" characters. For certificates with a very large DNS SAN list, CPU use could grow quadratically with the number of SAN entries and hostname labels. Because hostname verification runs before the certificate chain is built, this overhead can occur even when the certificate is not trusted.\n\nRed Hat rates this issue as Important. It affects Red Hat products that include the Go standard library crypto/x509 code from an affected Go toolchain version (before Go 1.25.11, or from Go 1.26.0 through Go 1.26.3). Applications and container images built with a fixed Go release (1.25.11 or later, or 1.26.4 or later) are not affected. Community distributions such as Fedora are also affected.\n\nUpstream fix: Go 1.25.11 and Go 1.26.4 (GO-2026-5037).",

"details": "A flaw was found in the Go standard library crypto/x509 package. When verifying a TLS certificate hostname, VerifyHostname processed each DNS Subject Alternative Name (SAN) entry in a loop and repeatedly split the candidate hostname on \".\" characters. For certificates with a very large DNS SAN list, CPU use could grow quadratically with the number of SAN entries and hostname labels. Because hostname verification runs before the certificate chain is built, this overhead can occur even when the certificate is not trusted.\n\nRed Hat rates this issue as Important. It affects Red Hat products that include the Go standard library crypto/x509 code from an affected Go toolchain version (before Go 1.25.11, or from Go 1.26.0 through Go 1.26.3). Applications and container images built with a fixed Go release (1.25.11 or later, or 1.26.4 or later) are not affected. Community distributions such as Fedora are also affected.\n\nUpstream fix: Go 1.25.11 and Go 1.26.4 (GO-2026-5037).",

"text": "A flaw was found in Envoy, an open source edge and service proxy. This vulnerability occurs when Envoy translates an HTTP/3 request that is complete at the transport layer but still carries a nonzero Content-Length into an HTTP/1 request for an upstream server. If the upstream server responds before fully reading the declared body, a subsequent Envoy-generated request can be misinterpreted as part of the previous one. This can lead to a request desynchronization, allowing an attacker to bypass security policies and access unauthorized resources.",
