Lifecycle Timeline
2Description
In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions prior to 12.6.1204.204, the affected applications lack proper validation of user-supplied data when parsing CO 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.
Analysis
In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions prior to 12.6.1204.204, the affected applications lack proper validation of user-supplied data when parsing CO files. Rated high severity (CVSS 8.4), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical Context
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions prior to 12.6.1204.204, the affected applications lack proper validation of user-supplied data when parsing CO 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. Affected products include: Ashlar Argon, Ashlar Cobalt, Ashlar Cobalt Share, Ashlar Lithium, Ashlar Xenon. Version information: prior to 12.6.1204.204.
Affected Products
Ashlar Argon, Ashlar Cobalt, Ashlar Cobalt Share, Ashlar Lithium, Ashlar Xenon.
Remediation
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
