Name of the Vulnerable Software and Affected Versions Ashlar-Vellum Cobalt (affected versions not specified)

Description This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of CO files due to the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this to execute code in the context of the current process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
