It uses GObjects and the glib main loop, to integrate well with GNOME applications, and also has a synchronous API, for use in threaded applications.\r\n\r\nSecurity Fix(es):\n\nA flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.(CVE-2025-14523)\n\nA flaw was found in libsoup's NTLM (NT LAN Manager) authentication module. When NTLM authentication is enabled, a local attacker can exploit a stack-based buffer overflow vulnerability in the md4sum() function. This allows the attacker to overwrite adjacent memory, which may result in arbitrary code execution with the privileges of the affected application.(CVE-2026-0719)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"libsoup","purl":"pkg:rpm/openEuler/libsoup&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.74.3-11.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["libsoup-2.74.3-11.oe2403sp1.aarch64.rpm","libsoup-debuginfo-2.74.3-11.oe2403sp1.aarch64.rpm","libsoup-debugsource-2.74.3-11.oe2403sp1.aarch64.rpm","libsoup-devel-2.74.3-11.oe2403sp1.aarch64.rpm"],"noarch":["libsoup-help-2.74.3-11.oe2403sp1.noarch.rpm"],"src":["libsoup-2.74.3-11.oe2403sp1.src.rpm"],"x86_64":["libsoup-2.74.3-11.oe2403sp1.x86_64.rpm","libsoup-debuginfo-2.74.3-11.oe2403sp1.x86_64.rpm","libsoup-debugsource-2.74.3-11.oe2403sp1.x86_64.rpm","libsoup-devel-2.74.3-11.oe2403sp1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1324"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-14523"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-0719"}],"database_specific":{"severity":"High"}}
