EulerOS 2.0 SP11 : golang (EulerOS-SA-2026-2245)

critical Nessus Plugin ID 319934

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 archive/zip uses a super-linear file name indexing algorithm that is invoked the first time a file in an archive is opened. This can lead to a denial of service when consuming a maliciously constructed ZIP archive.(CVE-2025-61728)

 url.Parse insufficiently validated the host/authority component and accepted some invalid URLs.(CVE-2026-25679)

 Actions which insert URLs into the content attribute of HTML meta tags are not escaped. This can allow XSS if the meta tag also has an http-equiv attribute with the value 'refresh'. A new GODEBUG setting has been added, htmlmetacontenturlescape, which can be used to disable escaping URLs in actions in the meta content attribute which follow 'url=' by setting htmlmetacontenturlescape=0.(CVE-2026-27142)

 Downloading and building modules with malicious version strings can cause local code execution. On systems with Mercurial (hg) installed, downloading modules from non-standard sources (e.g., custom domains) can cause unexpected code execution due to how external VCS commands are constructed. This issue can also be triggered by providing a malicious version string to the toolchain. On systems with Git installed, downloading and building modules with malicious version strings can allow an attacker to write to arbitrary files on the filesystem. This can only be triggered by explicitly providing the malicious version strings to the toolchain and does not affect usage of @latest or bare module paths.(CVE-2025-68119)

 The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.(CVE-2025-61726)

 During session resumption in crypto/tls, if the underlying Config has its ClientCAs or RootCAs fields mutated between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake.(CVE-2025-68121)

 Building a malicious file with cmd/go can cause can cause a write to an attacker-controlled file with partial control of the file content. The '#cgo pkg-config:' directive in a Go source file provides command-line arguments to provide to the Go pkg-config command. An attacker can provide a '--log-file' argument to this directive, causing pkg-config to write to an attacker-controlled location.(CVE-2025-61731)

Tenable has extracted the preceding description block directly from the EulerOS golang security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected golang packages.
