SerialiseValue in RenderDoc before 1.27 allows an Integer Overflow with a resultant Buffer Overflow.0xffffffff is sign-extended to 0xffffffffffffffff (SIZE_MAX) and then there is an attempt to add 1.

CVE-2023-33863 is a critical security vulnerability identified in the RenderDoc graphics debugging tool, affecting versions prior to 1.27. The vulnerability arises from an integer overflow in the SerialiseValue function. Specifically, when the value 0xffffffff is processed, it is sign-extended to 0xffffffffffffffff (SIZE_MAX on 64-bit systems), which leads to an integer overflow when the code attempts to add 1 to this value. This overflow results in a buffer overflow condition, where memory beyond the intended buffer is overwritten. Buffer overflows are a common vector for arbitrary code execution, allowing attackers to potentially execute malicious code with the privileges of the affected application. The vulnerability requires no authentication or user interaction, and the attack vector is network-based (AV:N), meaning it can be exploited remotely. The CVSS v3.1 base score of 9.8 reflects the critical nature of the vulnerability, with impacts rated high on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability’s characteristics suggest it could be weaponized quickly. RenderDoc is widely used by developers and companies involved in graphics programming, game development, and software debugging, making this vulnerability particularly relevant to those sectors. The lack of an official patch at the time of reporting necessitates immediate attention to mitigation strategies to prevent exploitation.
