| summary: Unbounded memory consumption when reading headers in archive/tar |
| description: |- |
| Reader.Read does not set a limit on the maximum size of file headers. A |
| maliciously crafted archive could cause Read to allocate unbounded amounts of |
| memory, potentially causing resource exhaustion or panics. After fix, |
| Reader.Read limits the maximum size of header blocks to 1 MiB. |
