This package contains plug-ins that are not tested well enough yet, or the code is not of good enough quality.\r\n\r\nSecurity Fix(es):\n\nA stack buffer overflow flaw was found in the GStreamer H.265 codec parser library (gst-plugins-bad). When parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from cpb_cnt_minus1[i] (the loop index) instead of the sub-layer 0 CPB count cpb_cnt_minus1[0] from the referenced Sequence Parameter Set. A crafted H.265 video file or stream can cause the parser to write beyond the bounds of stack-allocated CPB delay arrays, resulting in a crash or potential stack memory corruption.(CVE-2026-53702)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"gstreamer1-plugins-bad-free","purl":"pkg:rpm/openEuler/gstreamer1-plugins-bad-free&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.16.2-14.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["gstreamer1-plugins-bad-free-1.16.2-14.oe2203sp4.aarch64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-14.oe2203sp4.aarch64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-14.oe2203sp4.aarch64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-14.oe2203sp4.aarch64.rpm"],"src":["gstreamer1-plugins-bad-free-1.16.2-14.oe2203sp4.src.rpm"],"x86_64":["gstreamer1-plugins-bad-free-1.16.2-14.oe2203sp4.x86_64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-14.oe2203sp4.x86_64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-14.oe2203sp4.x86_64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-14.oe2203sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"gstreamer1-plugins-bad-free","purl":"pkg:rpm/openEuler/gstreamer1-plugins-bad-free&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.16.2-14.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["gstreamer1-plugins-bad-free-1.16.2-14.oe2403sp1.aarch64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-14.oe2403sp1.aarch64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-14.oe2403sp1.aarch64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-14.oe2403sp1.aarch64.rpm"],"src":["gstreamer1-plugins-bad-free-1.16.2-14.oe2403sp1.src.rpm"],"x86_64":["gstreamer1-plugins-bad-free-1.16.2-14.oe2403sp1.x86_64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-14.oe2403sp1.x86_64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-14.oe2403sp1.x86_64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-14.oe2403sp1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"gstreamer1-plugins-bad-free","purl":"pkg:rpm/openEuler/gstreamer1-plugins-bad-free&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.16.2-14.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["gstreamer1-plugins-bad-free-1.16.2-14.oe2403sp3.aarch64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-14.oe2403sp3.aarch64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-14.oe2403sp3.aarch64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-14.oe2403sp3.aarch64.rpm"],"src":["gstreamer1-plugins-bad-free-1.16.2-14.oe2403sp3.src.rpm"],"x86_64":["gstreamer1-plugins-bad-free-1.16.2-14.oe2403sp3.x86_64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-14.oe2403sp3.x86_64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-14.oe2403sp3.x86_64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-14.oe2403sp3.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"gstreamer1-plugins-bad-free","purl":"pkg:rpm/openEuler/gstreamer1-plugins-bad-free&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.16.2-7.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["gstreamer1-plugins-bad-free-1.16.2-7.oe2003sp4.aarch64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-7.oe2003sp4.aarch64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-7.oe2003sp4.aarch64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-7.oe2003sp4.aarch64.rpm"],"src":["gstreamer1-plugins-bad-free-1.16.2-7.oe2003sp4.src.rpm"],"x86_64":["gstreamer1-plugins-bad-free-1.16.2-7.oe2003sp4.x86_64.rpm","gstreamer1-plugins-bad-free-debuginfo-1.16.2-7.oe2003sp4.x86_64.rpm","gstreamer1-plugins-bad-free-debugsource-1.16.2-7.oe2003sp4.x86_64.rpm","gstreamer1-plugins-bad-free-devel-1.16.2-7.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2793"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53702"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}],"database_specific":{"severity":"Medium"}}
