CVE-2019-6245
CVSS v3.1
8.8
High
| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
svgpp version 1.2.3
Anti-Grain Geometry (AGG) version 2.4
Description
A problem exists in the
agg::cell aa::not equal function where dx is assigned the value of (x2 - x1). If dx is greater than or equal to dx limit, which is calculated as (16384 << poly subpixel shift), the function calls itself recursively. This can lead to a situation where (x2 - x1) is always larger than dx limit during recursion, resulting in continuous stack consumption.Recommendations
For svgpp version 1.2.3, consider disabling the
agg::cell aa::not equal function until a patch is available to prevent potential stack overflow issues.
For Anti-Grain Geometry (AGG) version 2.4, restrict the recursive calls in the agg::cell aa::not equal function to minimize the risk of exploitation.Exploit
