A use-after-free vulnerability was observed in Rp_toString function of Artifex Software, Inc. MuJS before 5c337af4b3df80cf967e4f9f6a21522de84b392a. A successful exploitation of this issue can lead to code execution or denial of service condition.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
