Azure RTOS FileX 数字错误漏洞
英文标题:
Azure RTOS FileX vulnerable to Buffer Offerflow
漏洞描述
中文描述:
Azure RTOS FileX是Azure RTOS开源的一个与 FAT 兼容的文件系统。 Azure RTOS FileX 6.2.0之前版本存在安全漏洞，该漏洞源于容错功能包括整数不足和溢出，可被利用来实现缓冲区溢出和修改内存内容。
英文描述:
Azure RTOS FileX is a FAT-compatible file system that’s fully integrated with Azure RTOS ThreadX. In versions before 6.2.0, the Fault Tolerant feature of Azure RTOS FileX includes integer under and overflows which may be exploited to achieve buffer overflow and modify memory contents. When a valid log file with correct ID and checksum is detected by the `_fx_fault_tolerant_enable` function an attempt to recover the previous failed write operation is taken by call of `_fx_fault_tolerant_apply_logs`. This function iterates through the log entries and performs required recovery operations. When properly crafted a log including entries of type `FX_FAULT_TOLERANT_DIR_LOG_TYPE` may be utilized to introduce unexpected behavior. This issue has been patched in version 6.2.0. A workaround to fix line 218 in fx_fault_tolerant_apply_logs.c is documented in the GHSA.
