Vulnerability Title
N/A
Vulnerability Description
The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers, a different vulnerability than CVE-2012-3404 and CVE-2012-3405.

GNU glibc 格式化打印功能权限许可和访问控制漏洞
Vulnerability Description
GNU C Library（又名glibc，libc6）是一种按照LGPL许可协议发布的开源免费的C语言编译程序。 GNU C Library 2.5和2.12他版本中的stdio-common/vfprintf.c文件中的‘vfprintf’函数中存在安全漏洞，该漏洞源于程序在分配SPECS数组时，没有正确限制alloca函数的使用。攻击者可通过使用positional参数的格式字符串和大量的格式说明符利用该漏洞绕过FORTIFY_SOURCE格式字符串保护机制，造成拒绝服务（崩溃）。
