ParquetSharp: Possible Stack Overflow When Reading a ParquetFile with Large Decimal Type Width
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| NuGet | ParquetSharp | >= 18.1.0, < 23.0.0.1 | 23.0.0.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
`DecimalConverter.ReadDecimal` makes a stackalloc using what might be an attacker-supplied value. If an attacker declares a decimal column with some unreasonable width, this could lead to a stack overflow. In a service environment, this would potentially take down a service.
This affects applications using ParquetSharp to read untrusted Parquet files in a network service.
