EulerOS 2.0 SP11 : libsoup (EulerOS-SA-2026-2213)

critical Nessus Plugin ID 319965

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability arises from non-RFC-compliant parsing in the soup_filter_input_stream_read_line() logic, where libsoup accepts malformed chunk headers, such as lone line feed (LF) characters instead of the required carriage return and line feed (CRLF). A remote attacker can exploit this without authentication or user interaction by sending specially crafted chunked requests. This allows libsoup to parse and process multiple HTTP requests from a single network message, potentially leading to information disclosure.(CVE-2026-1801)

 A flaw was found in libsoup's WebSocket frame processing when handling incoming messages. If a non-default configuration is used where the maximum incoming payload size is unset, the library may read memory outside the intended bounds. This can cause unintended memory exposure or a crash. Applications using libsoup's WebSocket support with this configuration may be impacted.(CVE-2026-0716)

 A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In certain build configurations, this could allow a remote attacker to access portions of server memory beyond the intended response. Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component.(CVE-2026-2443)

 A flaw was found in libsoup. An integer underflow vulnerability occurs when processing content with a zero-length resource, leading to a buffer overread. This can allow an attacker to potentially access sensitive information or cause an application level denial of service.(CVE-2026-2369)

Tenable has extracted the preceding description block directly from the EulerOS libsoup 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 libsoup packages.
