Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2025-14523)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. libsoup accepts duplicate Host: headers and implements a last-value-wins policy when soup_message_headers_get_one[_common] is used to construct the request URI, while many proxies and routers use the first Host: header for routing. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
2) Buffer access with incorrect length value (CVE-ID: CVE-2026-0716)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error in process_frame() function when handling WebSocket frames if a non-default configuration is used where the maximum incoming payload size is unset. A remote attacker can send specially crafted data to the application and execute arbitrary code on the system.
3) Stack-based buffer overflow (CVE-ID: CVE-2026-0719)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the md4sum() function of libsoup’s NTLM authentication module (SoupAuthNTLM) when handling NTLM authentication requests. A remote attacker can send specially crafted input to the application, trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) CRLF injection (CVE-ID: CVE-2026-1467)
The vulnerability allows a remote attacker to inject arbitrary data in server response.
The vulnerability exists due to insufficient validation of attacker-supplied data. A remote attacker can pass specially crafted HTTP request ta to the application containing CR-LF characters and modify application behavior.
5) Information disclosure (CVE-ID: CVE-2026-1539)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to library does not remove data from Proxy-Authorization header when following redirects. A remote attacker can gain access to sensitive information passed via the Proxy-Authorization header.
6) Stack-based buffer overflow (CVE-ID: CVE-2026-1761)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the soup_filter_input_stream_read_until() function when parsing multipart/form-data response. A remote attacker can send specially crafted data to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
