Summary

Red Hat Security Advisory: golang-github-openprinting-ipp-usb security update

Severity

Important

Notes

Topic: An update for golang-github-openprinting-ipp-usb is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: HTTP reverse proxy, backed by IPP-over-USB connection to device. It enables driverless support for USB devices capable of using IPP-over-USB protocol. Security Fix(es): * net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME (CVE-2026-33811) * crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries (CVE-2026-27145) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2026-27145

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.

7.5 (High)

CVE-2026-33811

A flaw was found in the `net` package of Go (golang), specifically when using the `LookupCNAME` function with the `cgo` DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name (CNAME) response. This can trigger a double-free of C memory, leading to a crash and a Denial of Service (DoS) for the affected application.

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.",

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).",

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).",

CVE-2026-27145 (GCVE-0-2026-27145)

Vulnerability from cvelistv5 – Published: 2026-06-02 22:01 – Updated: 2026-07-06 12:05

Title

Inefficient candidate hostname parsing in crypto/x509

Summary

(*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries. This caused strings.Split(host, ".") to execute repeatedly on the same input hostname. With a large DNS SAN list, verification costs scaled quadratically based on the number of SAN entries multiplied by the hostname's label count. Because x509.Verify validates hostnames before building the certificate chain, this overhead occurred even for untrusted certificates.
