{"id":"UBUNTU-CVE-2019-6245","details":"An issue was discovered in Anti-Grain Geometry (AGG) 2.4 as used in SVG++ (aka svgpp) 1.2.3. In the function agg::cell_aa::not_equal, dx is assigned to (x2 - x1). If dx \u003e= dx_limit, which is (16384 \u003c\u003c poly_subpixel_shift), this function will call itself recursively. There can be a situation where (x2 - x1) is always bigger than dx_limit during the recursion, leading to continual stack consumption.","modified":"2025-09-08T16:45:16Z","published":"2019-01-13T00:29:00Z","upstream":["CVE-2019-6245"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-6245"},{"type":"REPORT","url":"https://github.com/svgpp/svgpp/issues/70"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-6245"}],"affected":[{"package":{"name":"agg","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/agg@2.5+dfsg1-9+deb8u1build0.16.04.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.5+dfsg1-9+deb8u1build0.16.04.1"}]}],"versions":["2.5+dfsg1-9"],"ecosystem_specific":{"binaries":[{"binary_name":"libagg-dev","binary_version":"2.5+dfsg1-9+deb8u1build0.16.04.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-6245.json"}},{"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_name":"libsvgpp-dev","binary_version":"1.2.3+dfsg1-3ubuntu1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-6245.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"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":"medium"}]}
