Name of the Vulnerable Software and Affected Versions
pixman versions prior to 0.32.0
pixman version 0.22.0
Description
The issue is related to an integer underflow in the
pixman trapezoid valid macro in pixman.h in Pixman, which can be exploited to cause a denial of service (crash) via a negative bottom value. This can lead to disruption of protected information and can be exploited remotely.Recommendations
For pixman versions prior to 0.32.0, update to version 0.32.0 or later to resolve the issue.
For pixman version 0.22.0, consider disabling the
pixman trapezoid valid macro until a patch is available.
As a temporary workaround, restrict access to the vulnerable pixman package to minimize the risk of exploitation.Correção
