EulerOS 2.0 SP13 : golang (EulerOS-SA-2026-2291)

critical Nessus Plugin ID 320277

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 :

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)

On Unix platforms, when listing the contents of a directory using File.ReadDir or File.Readdir the returned FileInfo could reference a file outside of the Root in which the File was opened. The impact of this escape is limited to reading metadata provided by lstat from arbitrary locations on the filesystem without permitting reading or writing files outside the root.(CVE-2026-27139)

Arithmetic over induction variables in loops were not correctly checked for underflow or overflow. As a result, the compiler would allow for invalid indexing to occur at runtime, potentially leading to memory corruption.(CVE-2026-27143)

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.
