Name of the Vulnerable Software and Affected Versions
Qt qtbase versions 5.11.x through 5.12.4
Description
The issue is related to an out-of-bounds memory access in the
generateDirectionalRuns() function. This can be exploited by attackers to cause a denial of service, crashing an application via a text file containing many directional characters. The vulnerability can be exploited remotely, allowing an attacker to cause a denial of service.Recommendations
For Qt qtbase versions 5.11.x through 5.12.4, update to version 5.12.5 or later to resolve the issue.
As a temporary workaround, consider restricting the use of text files containing directional characters to minimize the risk of exploitation.
