Description The issue is an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file. This allows attackers to execute arbitrary code.

Recommendations For versions 22.001.20085 and earlier, update to a version later than 22.001.20085 to resolve the issue. For versions 20.005.3031x and earlier, update to a version later than 20.005.3031x to resolve the issue. For versions 17.012.30205 and earlier, update to a version later than 17.012.30205 to resolve the issue. As a temporary workaround, consider avoiding the opening of files from untrusted sources to minimize the risk of exploitation.
