renderdoc

RenderDoc before 1.27 allows local privilege escalation via a symlink attack. It relies on the /tmp/RenderDoc directory regardless of ownership.

CVE-2023-33865 is a local privilege escalation vulnerability affecting RenderDoc, a popular graphics debugging tool, in versions prior to 1.27. The vulnerability stems from RenderDoc's reliance on the /tmp/RenderDoc directory without verifying the directory's ownership or permissions. This design flaw allows an attacker with local access to create a symbolic link (symlink) pointing /tmp/RenderDoc to an arbitrary location. When RenderDoc operates on this directory, it may inadvertently perform privileged operations on files or directories controlled by the attacker. This symlink attack can lead to unauthorized modification or replacement of critical files, resulting in full privilege escalation. The CVSS 3.1 base score of 7.8 reflects the high impact on confidentiality, integrity, and availability, combined with low attack complexity and the requirement for only limited privileges and no user interaction. Although no exploits are currently known in the wild, the vulnerability is significant due to the common use of RenderDoc in development environments and the potential for attackers to leverage local access to gain administrative control. The weakness is categorized under CWE-59 (Improper Link Resolution Before File Access), emphasizing the importance of secure handling of temporary directories and symlinks. Mitigation primarily involves updating RenderDoc to version 1.27 or later, where this issue is addressed, and enforcing strict permissions and monitoring on the /tmp directory to prevent unauthorized symlink creation.

CVE-2023-33865: n/a

StreamReader::ReadFromExternal in RenderDoc before 1.27 allows an Integer Overflow with a resultant Buffer Overflow. It uses uint32_t(m_BufferSize-m_InputSize) even though m_InputSize can exceed m_BufferSize.

CVE-2023-33864 is a critical vulnerability identified in RenderDoc, a popular graphics debugging tool used primarily by developers. The vulnerability resides in the StreamReader::ReadFromExternal function, where an integer overflow occurs due to the use of uint32_t(m_BufferSize - m_InputSize) without proper validation. Since m_InputSize can exceed m_BufferSize, this calculation can wrap around, causing an integer overflow that leads to a buffer overflow condition. This buffer overflow can be exploited to execute arbitrary code, corrupt memory, or cause denial of service. The vulnerability is remotely exploitable without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact on confidentiality, integrity, and availability is high, making it a critical security issue. No patches or fixes are currently linked, and no known exploits have been reported in the wild yet. The CWE associated is CWE-190 (Integer Overflow or Wraparound), which is a common root cause for buffer overflow vulnerabilities. Organizations using RenderDoc in their development environments or pipelines should be aware of this flaw and prepare to apply patches or mitigations once available.

CVE-2023-33864: n/a

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.
