Summary
A use-after-free vulnerability exists in Foxit Reader 12.1.2.15332 related to handling the destruction of annotations. Maliciously crafted Javascript code in a PDF document can trigger reuse of a previously freed object, leading to memory corruption and potential arbitrary code execution.
Risk Assessment
An attacker can trick the user into opening a malicious file or visiting a specially crafted site, which poses a risk of executing unauthorized code on the user's system.
Recommendation
It is recommended to update Foxit Reader to the latest version and avoid opening PDF files from unknown sources. Consider disabling the browser plugin if it is not needed.

Original NVD description (English source)
A use-after-free vulnerability exists in the way Foxit Reader 12.1.2.15332 handles destroying annotations. Specially crafted Javascript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.
