Details

Memory safety bugs present in Firefox 135, Thunderbird 135, Firefox ESR 115.20, Firefox ESR 128.7, and Thunderbird 128.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 136, Firefox ESR < 115.21, and Firefox ESR < 128.8.

Mitigation
Architecture and Design

Ensure that memory regions are isolated as intended and that access control (read/write) policies are used by hardware to protect privileged software.

Mitigation
Implementation
  • For all of the programmable memory protection regions, the memory protection unit (MPU) design can define a priority scheme.
  • For example: if three memory regions can be programmed (Region_0, Region_1, and Region_2), the design can enforce a priority scheme, such that, if a system address is within multiple regions, then the region with the lowest ID takes priority and the access-control policy of that region will be applied. In some MPU designs, the priority scheme can also be programmed by trusted software.
  • Hardware logic or trusted firmware can also check for region definitions and block programming of memory regions with overlapping addresses.
  • The memory-access-control-check filter can also be designed to apply a policy filter to all of the overlapping ranges, i.e., if an address is within Region_0 and Region_1, then access to this address is only granted if both Region_0 and Region_1 policies allow the access.
CAPEC-456: Infected Memory

An adversary inserts malicious logic into memory enabling them to achieve a negative impact. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems that are still under development and part of the supply chain.

CAPEC-679: Exploitation of Improperly Configured or Implemented Memory Protections

An adversary takes advantage of missing or incorrectly configured access control within memory to read/write data or inject malicious code into said memory.
