{"id":"UBUNTU-CVE-2026-29508","details":"ReadyMedia (formerly MiniDLNA) versions 1.3.0 through 1.3.3 contain a stack-based buffer overflow vulnerability that allows remote attackers to corrupt stack memory by crafting a malicious DFF audio file with an oversized PROP chunk size value that is used unvalidated to allocate a variable-length stack array and read file data into it. Attackers can place a crafted DFF file in a directory monitored by ReadyMedia to trigger automatic parsing via inotify, achieving remote code execution on unprotected builds or denial of service on hardened builds with stack protections.","modified":"2026-11-04T03:30:12.576437559Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-29508"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-29508"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-29508"},{"type":"REPORT","url":"https://sourceforge.net/projects/minidlna/"},{"type":"REPORT","url":"https://www.asus.com/networking-iot-servers/wifi-routers/asus-gaming-routers/rt-ax86u/helpdesk_bios?model2Name=RT-AX86-Series-RT-AX86U-RT-AX86S"},{"type":"REPORT","url":"https://www.kr3bz.wtf/posts/minidlna-unbounded-vla-to-rce/"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/readymedia-stack-buffer-overflow-via-dff-parser"}],"affected":[{"package":{"name":"minidlna","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/minidlna?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.4+dfsg-4build1","1.1.5+dfsg-1","1.1.5+dfsg-2","1.1.5+dfsg-2ubuntu0.1","1.1.5+dfsg-2ubuntu0.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"minidlna","binary_version":"1.1.5+dfsg-2ubuntu0.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29508.json"}},{"package":{"name":"minidlna","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/minidlna?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.0+dfsg-2","1.2.1+dfsg-1","1.2.1+dfsg-1ubuntu0.18.04.1","1.2.1+dfsg-1ubuntu0.18.04.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"minidlna","binary_version":"1.2.1+dfsg-1ubuntu0.18.04.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29508.json"}},{"package":{"name":"minidlna","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/minidlna?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.1+dfsg-1build1","1.2.1+dfsg-1ubuntu0.20.04.1","1.2.1+dfsg-1ubuntu0.20.04.2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.1+dfsg-1ubuntu0.20.04.2","binary_name":"minidlna"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29508.json"}},{"package":{"name":"minidlna","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/minidlna?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.0+dfsg-2","1.3.0+dfsg-2.1","1.3.0+dfsg-2.1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"minidlna","binary_version":"1.3.0+dfsg-2.1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29508.json"}},{"package":{"name":"minidlna","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/minidlna?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.3+dfsg-0.1","1.3.3+dfsg-0.2","1.3.3+dfsg-1","1.3.3+dfsg-1build1","1.3.3+dfsg-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"minidlna","binary_version":"1.3.3+dfsg-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29508.json"}},{"package":{"name":"minidlna","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/minidlna?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.3+dfsg-1.1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"minidlna","binary_version":"1.3.3+dfsg-1.1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29508.json"}},{"package":{"name":"minidlna","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/minidlna?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.3+dfsg-1.1build1","1.3.3+dfsg-1.1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"minidlna","binary_version":"1.3.3+dfsg-1.1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29508.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
