CVE-2023-48626

Code execution via malicious file opening

Published Dec 13, 2023 · Updated Aug 2, 2024

Out-of-bounds write in Adobe Substance 3D Sampler 4.2.1 and earlier allows context-dependent attackers to execute code via a malicious file. Adobe has not disclosed the affected parser, file format, or memory-boundary error that permits the write beyond an allocated buffer. Exploitation requires a victim to open the crafted file, after which code runs with the victim's current-user privileges.
