{"id":"DEBIAN-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":"2026-09-09T07:02:27.063464952Z","published":"2019-01-13T00:29:00.570Z","upstream":["CVE-2019-6247"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2019-6247"}],"affected":[{"package":{"name":"svgpp","ecosystem":"Debian:12","purl":"pkg:deb/debian/svgpp?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.0+dfsg1-6","1.3.1+dfsg1-1","1.3.1+dfsg1-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2019-6247.json"}},{"package":{"name":"svgpp","ecosystem":"Debian:13","purl":"pkg:deb/debian/svgpp?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.0+dfsg1-6","1.3.1+dfsg1-1","1.3.1+dfsg1-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2019-6247.json"}},{"package":{"name":"svgpp","ecosystem":"Debian:14","purl":"pkg:deb/debian/svgpp?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.0+dfsg1-6","1.3.1+dfsg1-1","1.3.1+dfsg1-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2019-6247.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
