{"id":"OESA-2026-4439","summary":"libsoup security update","details":"libsoup is an HTTP client/server library for GNOME. 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)","modified":"2026-10-22T14:45:04.857722460Z","published":"2026-10-22T14:35:09Z","upstream":["CVE-2026-102558","CVE-2026-102560"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4439"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102558"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102560"}],"affected":[{"package":{"name":"libsoup","ecosystem":"openEuler:24.03-LTS-SP3","purl":"pkg:rpm/openEuler/libsoup&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.74.3-30.oe2403sp3"}]}],"ecosystem_specific":{"src":["libsoup-2.74.3-30.oe2403sp3.src.rpm"],"x86_64":["libsoup-2.74.3-30.oe2403sp3.x86_64.rpm","libsoup-debuginfo-2.74.3-30.oe2403sp3.x86_64.rpm","libsoup-debugsource-2.74.3-30.oe2403sp3.x86_64.rpm","libsoup-devel-2.74.3-30.oe2403sp3.x86_64.rpm"],"aarch64":["libsoup-2.74.3-30.oe2403sp3.aarch64.rpm","libsoup-debuginfo-2.74.3-30.oe2403sp3.aarch64.rpm","libsoup-debugsource-2.74.3-30.oe2403sp3.aarch64.rpm","libsoup-devel-2.74.3-30.oe2403sp3.aarch64.rpm"],"noarch":["libsoup-help-2.74.3-30.oe2403sp3.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4439.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}]}
