Technical Description
In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share v12 SP0 Build (1204.77), the affected applications lack proper validation of user-supplied data when parsing XE files. This could lead to an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
Remediation
Check the references section for vendor advisories and patches from ashlar. Update cobalt to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
