Description
Ashlar-Vellum Cobalt VC6 File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of VC6 files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25704.

CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is an integer overflow in the parsing of VC6 files in Ashlar-Vellum Cobalt. It occurs because the software does not properly validate user-supplied data, leading to an integer overflow before buffer allocation. This flaw allows remote attackers to execute arbitrary code by tricking a user into opening a malicious file or visiting a malicious page.


How can this vulnerability impact me? :

If exploited, this vulnerability can allow an attacker to execute arbitrary code on your system with the privileges of the current process. This could lead to unauthorized actions such as data theft, system compromise, or further malware installation. Exploitation requires user interaction, such as opening a malicious file or visiting a malicious webpage.
