{"id":"UBUNTU-CVE-2019-6247","details":"An issue was discovered in Anti-Grain Geometry (AGG) 2.4 as used in SVG++ (aka svgpp) 1.2.3. A heap-based buffer overflow bug in svgpp_agg_render may lead to code execution. In the render_scanlines_aa_solid function, the blend_hline function is called repeatedly multiple times. blend_hline is equivalent to a loop containing write operations. Each call writes a piece of heap data, and multiple calls overwrite the data in the heap.","modified":"2025-09-08T16:45:16Z","published":"2019-01-13T00:29:00Z","upstream":["CVE-2019-6247"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-6247"},{"type":"REPORT","url":"https://github.com/svgpp/svgpp/issues/70"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-6247"}],"affected":[{"package":{"name":"svgpp","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/svgpp@1.2.3+dfsg1-3ubuntu1+esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.3+dfsg1-3","1.2.3+dfsg1-3ubuntu1","1.2.3+dfsg1-3ubuntu1+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.3+dfsg1-3ubuntu1+esm1","binary_name":"libsvgpp-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-6247.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"negligible"}]}
