		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">graphviz security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for graphviz is now available for openEuler-20.03-LTS-SP1.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Graphviz is open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

Security Fix(es):

Buffer Overflow in Graphviz Graph Visualization Tools from commit ID f8b9e035 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by loading a crafted file into the &quot;lib/common/shapes.c&quot; component.(CVE-2020-18032)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for graphviz is now available for openEuler-20.03-LTS-SP1.

openEuler Security has rated this update as having a security impact of critical. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
