Boost _ Firedancer v0.1 34682 - [Blockchain_DLT - Medium] DoS in shreds validation
Submitted on Tue Aug 20 2024 20:21:43 GMT-0400 (Atlantic Standard Time) by @Swift77057 for Boost | Firedancer v0.1
Report ID: #34682
Report type: Blockchain/DLT
Report severity: Medium
Target: https://github.com/firedancer-io/firedancer/tree/e60d9a6206efaceac65a5a2c3a9e387a79d1d096
Impacts:
Liveness issues that cause Firedancer v0.1 validators to crash or be unavailable
Description
Brief/Intro
This is similar to report 34501, where a check in the shred tile is missing that causes the solana-labs tile to crash.
Vulnerability Details
Like in the previous report, I found another shred that causes a panic in fd_ext_blockstore_insert_shreds.
Basically, the parent_off field of a data shred is not checked by fd at all. Setting this field to a value higher than the shred's slot triggers an error here:
fn parent(&self) -> Result<Slot, Error> {
let slot = self.common_header().slot;
let parent_offset = self.data_header().parent_offset;
if parent_offset == 0 && slot != 0 {
return Err(Error::InvalidParentOffset {
slot,
parent_offset,
});
}
slot.checked_sub(Slot::from(parent_offset))
.ok_or(Error::InvalidParentOffset {
slot,
parent_offset,
})
}This error then causes a panic due to the unwrap in fd_ext_blockstore_insert_shreds.
Note that this bug works, even if the flags check in previous report is fixed.
Impact Details
DoS
Proof of concept
Proof of Concept
Apply the patch and send the malicious shred.
