An Out of Bounds Write occurs when the native library attempts PDF rendering, which can be exploited to achieve memory corruption and potentially arbitrary code execution.
During PDF document processing, the application's native library performs a write outside the boundaries of the allocated memory buffer (Out-of-Bounds Write, CWE-787/CWE-119). A malformed PDF file can trigger this flaw, leading to process memory corruption. The result of corruption may be a takeover of control over the program's execution flow and execution of arbitrary code.
An attacker can gain full control over the victim's device by executing arbitrary code (RCE), and can also compromise the confidentiality, integrity, and availability of data — which corresponds to the highest ratings in all three CVSS categories.
Apply patches available from the vendor according to the references. It is also recommended to avoid opening untrusted PDF files in the application until the update is deployed.
