Vulnerability Description
SystemTap 1.0, when the --unprivileged option is used, does not properly restrict certain data sizes, which allows local users to (1) cause a denial of service or gain privileges via a print operation with a large number of arguments that trigger a kernel stack overflow, (2) cause a denial of service via crafted DWARF expressions that trigger a kernel stack frame overflow, or (3) cause a denial of service (infinite loop) via vectors that trigger creation of large unwind tables, related to Common Information Entry (CIE) and Call Frame Instruction (CFI) records.

SystemTap 无特权模式 多个拒绝服务漏洞
Vulnerability Description
当无特权模式被使用时，SystemTap 1.0版本没有正确的限制特定数据的大小，这使得(1)本地用户可以借助带有大量参数的一个打印操作，引起拒绝服务或获得特权。这些参数会触发内核栈溢出；(2)本地用户可以借助特定的会触发内核栈溢出的DWARF表述，引起拒绝服务攻击；或(3)本地用户可以借助会触发创建大的展开表格的参数，引起拒绝服务攻击(死循环)。这些漏洞与Common Information Entry (CIE)和Call Frame Instruction (CFI)记录有关。
