{"id":"UBUNTU-CVE-2026-35469","details":"spdystream is a Go library for multiplexing streams over SPDY connections. In versions 0.5.0 and below, the SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. Three allocation paths are affected: the SETTINGS frame entry count, the header count in parseHeaderValueBlock, and individual header field sizes — all read as 32-bit integers and used directly as allocation sizes with no bounds checking. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into large attacker-controlled values. A remote peer that can send SPDY frames to a service using spdystream can exhaust process memory and cause an out-of-memory crash with a single crafted control frame. This issue has been fixed in version 0.5.1.","modified":"2026-06-30T18:17:58.704983749Z","published":"2026-04-16T22:16:00Z","upstream":["CVE-2026-35469"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35469"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35469"},{"type":"REPORT","url":"https://github.com/moby/spdystream/security/advisories/GHSA-pc3f-x583-g7j2"}],"affected":[{"package":{"name":"golang-github-docker-spdystream","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/golang-github-docker-spdystream?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20151103.0.4d80814-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-docker-spdystream-dev","binary_version":"0.0~git20151103.0.4d80814-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35469.json"}},{"package":{"name":"golang-github-docker-spdystream","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/golang-github-docker-spdystream?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20151103.0.4d80814-1","0.0~git20151103.0.4d80814-2"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-docker-spdystream-dev","binary_version":"0.0~git20151103.0.4d80814-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35469.json"}},{"package":{"name":"golang-github-docker-spdystream","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/golang-github-docker-spdystream?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20151103.0.4d80814-2","0.0~git20181023.6480d4a-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0~git20181023.6480d4a-1","binary_name":"golang-github-docker-spdystream-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35469.json"}},{"package":{"name":"golang-github-docker-spdystream","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-docker-spdystream?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-docker-spdystream-dev","binary_version":"0.2.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35469.json"}},{"package":{"name":"golang-github-docker-spdystream","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-docker-spdystream?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.2.0-1","binary_name":"golang-github-docker-spdystream-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35469.json"}},{"package":{"name":"golang-github-docker-spdystream","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/golang-github-docker-spdystream?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-docker-spdystream-dev","binary_version":"0.5.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35469.json"}},{"package":{"name":"golang-github-docker-spdystream","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-github-docker-spdystream?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-docker-spdystream-dev","binary_version":"0.5.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35469.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
