GHSA-G4RW-8M5Q-6453

Vulnerability from github – Published: 2021-08-25 20:45 – Updated: 2023-06-13 20:26
VLAI
Summary
Out of bounds access in rgb
Details

Affected versions of rgb crate allow viewing and modifying data of any type T wrapped in RGB as bytes, and do not correctly constrain RGB and other wrapper structures to the types for which it is safe to do so.

Safety violation possible for a type wrapped in RGB and similar wrapper structures:

  • If T contains padding, viewing it as bytes may lead to exposure of contents of uninitialized memory.
  • If T contains a pointer, modifying it as bytes may lead to dereferencing of arbitrary pointers.
  • Any safety and/or validity invariants for T may be violated.

The issue was resolved by requiring all types wrapped in structures provided by RGB crate to implement an unsafe marker trait.

Vulnerability from github – Published: 2022-05-13 01:37 – Updated: 2022-05-13 01:37
VLAI
Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 8.3.1.21155. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the remove method of XFAScriptObject objects. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5017.
