CVE-2025-11464

Ashlar-Vellum Cobalt VS 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 in that the target must visit a malicious page or open a malicious file.

A use-after-free vulnerability in Ashlar-Vellum Cobalt during CO file parsing allows remote attackers to execute arbitrary code. User interaction is required — the victim must visit a malicious page or open a malicious file. The flaw results from the lack of validating an object's existence before performing operations on it.

Vulnerability in Ashlar-Vellum Cobalt XE while parsing XE files allows remote code execution. Lack of validation can lead to integer overflow before buffer allocation. User interaction is required, such as visiting a malicious page or opening a file.

Remote code execution vulnerability in Ashlar-Vellum Cobalt when parsing XE files. It results from lack of validation of user-supplied data, leading to an out-of-bounds read past the end of an allocated data structure. Requires user interaction (visiting a malicious page or opening a malicious file).

Remote code execution vulnerability in Ashlar-Vellum Cobalt when parsing XE files. It results from lack of validation of user-supplied data, leading to a type confusion condition. Requires user interaction (visiting a malicious page or opening a malicious file).
