It is suggested to upgrade the affected component.

Detailsinfo

A vulnerability, which was classified as problematic, was found in sigstore-java up to 1.1.x. This affects an unknown code. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on integrity. The summary by CVE is:

sigstore-java is a sigstore java client for interacting with sigstore infrastructure. sigstore-java has insufficient verification for a situation where a bundle provides a invalid signature for a checkpoint. This bug impacts clients using any variation of KeylessVerifier.verify(). Currently checkpoints are only used to ensure the root hash of an inclusion proof was provided by the log in question. Failing to validate that means a bundle may provide an inclusion proof that doesn't actually correspond to the log in question. This may eventually lead a monitor/witness being unable to detect when a compromised logs are providing different views of themselves to different clients. There are other mechanisms right now that mitigate this, such as the signed entry timestamp. Sigstore-java currently requires a valid signed entry timestamp. By correctly verifying the signed entry timestamp we can make certain assertions about the log signing the log entry (like the log was aware of the artifact signing event and signed it). Therefore the impact on clients that are not monitors/witnesses is very low. This vulnerability is fixed in 1.2.0.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2024-54140 since 11/29/2024. The exploitability is told to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.

Upgrading to version 1.2.0 eliminates this vulnerability. Applying the patch 23fb4885e6704a5df4977f7acf253a745349edf9 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
