Description
Ashlar-Vellum Cobalt CO File Parsing Heap-based Buffer 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 CO files. The issue results from 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 vulnerability to execute code in the context of the current process. Was ZDI-CAN-26628.

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

This vulnerability is a heap-based buffer overflow in Ashlar-Vellum Cobalt's CO file parsing functionality. It occurs because the software does not properly validate the length of user-supplied data before copying it into a heap-based buffer. Exploiting this flaw requires user interaction, such as visiting a malicious page or opening a malicious file, and allows remote attackers to execute arbitrary code within the context of the affected process.


How can this vulnerability impact me? :

If exploited, this vulnerability can allow an attacker to execute arbitrary code remotely on your system with the privileges of the affected application. This can lead to unauthorized control over the system, data compromise, or disruption of services.
