Description

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 VC6 files. This could lead to a heap-based buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
