Vulnerability Title
N/A
Vulnerability Description
Arm Compiler 5 through 5.06u6 has an error in a stack protection feature designed to help spot stack-based buffer overflows in local arrays. When this feature is enabled, a protected function writes a guard value to the stack prior to (above) any vulnerable arrays in the stack. The guard value is checked for corruption on function return; corruption leads to an error-handler call. In certain circumstances, the reference value that is compared against the guard value is itself also written to the stack (after any vulnerable arrays). The reference value is written to the stack when the function runs out of registers to use for other temporary data. If both the reference value and the guard value are written to the stack, then the stack protection will fail to spot corruption when both values are overwritten with the same value. For both the reference value and the guard value to be corrupted, there would need to be both a buffer overflow and a buffer underflow in the vulnerable arrays (or some other vulnerability that causes two separated stack entries to be corrupted).

ARM Compiler 缓冲区错误漏洞
Vulnerability Description
ARM Compiler是英国ARM公司的一个用于编译生成ARM架构应用的工具。 Arm Compiler 5版本5.06u6版本存在安全漏洞，该漏洞源于堆栈保护特性中有一个错误，这个特性被设计用来帮助发现本地数组中基于堆栈的缓冲区溢出。当启用此特性时，受保护函数在堆栈中任何易受攻击的数组之前(上面)写入一个保护值到堆栈。在函数返回时检查守卫值是否损坏;损坏会导致错误处理程序调用。
