Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Android versions 8.0 through 10

Description The issue is related to improper input validation in the handleRun function of TextLine.java, which can cause an application crash. This can lead to a remote denial of service when processing Unicode, with no additional execution privileges needed. User interaction is not required for exploitation.

Recommendations For Android versions 8.0 through 10, consider restricting the processing of Unicode input to minimize the risk of exploitation until a patch is available. As a temporary workaround, disabling the handleRun function in TextLine.java may help prevent the application crash. However, this should be done with caution as it may affect the functionality of the application. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
