CVE-2019-18281

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.
