pitrou opened a new issue, #49896: URL: https://github.com/apache/arrow/issues/49896
### Describe the bug, including details regarding any error messages, version, and platform. IO methods like `ReadAt` can return less bytes than asked for if the file is too short, but the IPC reader doesn't always detect for this situation. On invalid IPC files, this can produce issues down the road such as half-initialized buffers and large processing times (with a potential denial of service). This issue was detected by OSS-Fuzz: https://issues.oss-fuzz.com/issues/489758017 ### Component(s) C++ -- This is an automated message from the Apache Git Service.
