Mô tả CVE
In Eclipse OpenJ9 versions prior to 0.63.0, the JITServer component fails to perform cross-field validation on attacker-controlled `_size`, `_paddingSize`, and `_dataOffset` fields during `DataDescriptor` message deserialization. An unauthenticated remote attacker can send a crafted network payload that triggers an unsigned integer underflow in `DataDescriptor::getPayloadSize()` and `DataDescriptor::getNextDescriptor()`. This results in an out-of-bounds heap read and an immediate process crash (SIGSEGV), causing a denial of service.
Thông tin CVE
Điểm yếu liên quan
| Tên điểm yếu | Nguồn | |
|---|---|---|
| Out-of-bounds Read The product reads data past the end, or before the beginning, of the intended buffer. |
||
| Integer Underflow (Wrap or Wraparound) The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result. |
