Vulnerability Title
N/A
Vulnerability Description
The TSB I-TLB load implementation in arch/sparc/kernel/tsb.S in the Linux kernel before 2.6.33 on the SPARC platform does not properly obtain the value of a certain _PAGE_EXEC_4U bit and consequently does not properly implement a non-executable stack, which makes it easier for context-dependent attackers to exploit stack-based buffer overflows via a crafted application.

Vulnerability Title
Linux kernel 'TSB I-TLB'负荷实现缓冲区错误漏洞
Vulnerability Description
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 在SPARC平台上运行的Linux内核中，arch/sparc/kernel/tsb.S的TSB I-TLB负荷实现无法正确获得_PAGE_EXEC_4U位的值，并因此无法正确实现不可执行的堆栈，上下文依赖的攻击者可以通过特制的应用利用基于堆栈的缓冲区溢出。
