An out-of-bounds read issue was addressed with improved input validation. Processing a maliciously crafted font file may lead to arbitrary code execution.

A memory corruption issue was addressed with improved state management. Processing a maliciously crafted text file may lead to arbitrary code execution.

A use after free issue was addressed with improved memory management, which may allow a malicious application to elevate privileges.

An out-of-bounds write issue was addressed with improved input validation. Processing a maliciously crafted font file may lead to arbitrary code execution.

A sandboxed process may be able to circumvent sandbox restrictions. This issue was addressed with improved entitlements.

The issue involves an out-of-bounds read that can be addressed with improved input validation. A local user may be able to cause unexpected system termination or read kernel memory.

This issue allows remote attackers to redirect users to an external resource on affected installations. User interaction is required, as the target must be within a chat session with the attacker. The flaw exists within the parsing of a user's profile, specifically in the failure to properly validate a user's name, stored in the `name` variable. An attacker can leverage this, potentially in conjunction with other issues, to execute code in the context of the current process.

The issue involves an out-of-bounds read that can be addressed with improved bounds checking. This allows an application to potentially read restricted memory, which could lead to information disclosure.

A logic issue was addressed with improved restrictions.
