Title
Concurrent GSS-TSIG messages corrupt memory
Summary
Replaying GSS-TSIG signed UDP messages can result in memory corruption in "`named`". An attacker who can capture a previously signed UDP message can replay it while the negotiated TSIG key is still valid. By also sending crafted queries to a zone the attacker controls, the attacker may potentially achieve remote code execution.
This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.29, 9.21.0 through 9.21.26, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.29-S1.

Title
Pixar Animation Studio OpenUSD Crate File Parsing Double Free Remote Code Execution Vulnerability
Summary
Pixar Animation Studio OpenUSD Crate File Parsing Double Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Pixar Animation Studio OpenUSD. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of USDC and USDZ files. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-30428.

Mitigation
Architecture and Design
Choose a language that provides automatic memory management.
Mitigation
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Implementation
Use a static analysis tool to find double free instances.
