Lifecycle Timeline
1DescriptionNVD
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.
AnalysisAI
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. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
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 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. Affected products include: Ashlar Cobalt, Ashlar Graphite, Ashlar Xenon, Ashlar Argon, Ashlar Lithium.
RemediationAI
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).
