SCA: security update for github.com/sigstore/cosign/v2 (GHSA-88jx-383q-w4qc)

medium Tenable Cloud Security Plugin ID 412548

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Cosign provides code signing and transparency for containers and binaries. Prior to version 2.2.4, a
remote image with a malicious attachment can cause denial of service of the host machine running Cosign.
This can impact other services on the machine that rely on having memory available such as a Redis
database which can result in data loss. It can also impact the availability of other services on the
machine that will not be available for the duration of the machine denial. The root cause of this issue is
that Cosign reads the attachment from a remote image entirely into memory without checking the size of the
attachment first. As such, a large attachment can make Cosign read a large attachment into memory; If the
attachments size is larger than the machine has memory available, the machine will be denied of service.
The Go runtime will make a SigKill after a few seconds of system-wide denial. This issue can allow a
supply-chain escalation from a compromised registry to the Cosign user: If an attacher has compromised a
registry or the account of an image vendor, they can include a malicious attachment and hurt the image
consumer. Version 2.2.4 contains a patch for the vulnerability. (CVE-2024-29902)
