Octobox is software for managing GitHub notifications. A user of the system can provide a specifically crafted search query string that will trigger a ReDoS vulnerability.

A buffer overflow was discovered in the URL-authentication backend. If the backend is enabled, any malicious HTTP client can send a request for a specific resource including a crafted header, leading to denial of service and potentially remote code execution.

A remote code execution issue exists in the way the Chakra scripting engine handles objects in memory. This could allow an attacker to corrupt memory and execute arbitrary code in the context of the current user, potentially gaining the same user rights as the current user. If the current user has administrative rights, an attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights.
