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 was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data.(CVE-2026-102558)\n\nA flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.(CVE-2026-102560)\n\nA flaw was found in libsoup. An unsigned integer underflow in the soup_filter_input_stream_read_until() function causes a heap buffer over-read when parsing multipart HTTP responses. A malicious HTTP server can exploit this by sending a crafted multipart response, potentially causing the client application to crash or disclose sensitive heap memory.(CVE-2026-66337)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"libsoup","purl":"pkg:rpm/openEuler/libsoup&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.74.2-27.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["libsoup-2.74.2-27.oe2203sp4.aarch64.rpm","libsoup-debuginfo-2.74.2-27.oe2203sp4.aarch64.rpm","libsoup-debugsource-2.74.2-27.oe2203sp4.aarch64.rpm","libsoup-devel-2.74.2-27.oe2203sp4.aarch64.rpm"],"noarch":["libsoup-help-2.74.2-27.oe2203sp4.noarch.rpm"],"src":["libsoup-2.74.2-27.oe2203sp4.src.rpm"],"x86_64":["libsoup-2.74.2-27.oe2203sp4.x86_64.rpm","libsoup-debuginfo-2.74.2-27.oe2203sp4.x86_64.rpm","libsoup-debugsource-2.74.2-27.oe2203sp4.x86_64.rpm","libsoup-devel-2.74.2-27.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4441"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102558"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102560"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66337"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}],"database_specific":{"severity":"High"}}
