CVE-2022-29522

Code execution via simulator use-after-free

Published Jun 14, 2022 · Updated Aug 3, 2024

Use-after-free in the V-SFT simulator before 6.1.6.0 allows attackers to disclose information or execute code through a crafted image file. Published advisories identify the simulator as the locus but do not disclose the freed object, function, or image-parsing operation. Exploitation requires a user to open the file, after which code runs in the user's application context or simulator memory is exposed.
