BUGTRAQ ID: 24845 CVE ID:CVE-2007-3107 CNCVE ID:CNCVE-20073107 Linux PowerPC是一款嵌入式Linux操作系统。 Linux PowerPC存在一个信号处理缺陷，本地攻击者可以利用漏洞对系统进行拒绝服务攻击。 在restore_sigcontext中__copy_from_user调用存在页错误或计时器中断，此操作写入current->thread.fpr和current->thread.vr，由于在拷贝后没有清理MSR_FP和MSR_VEC，在拷贝过程中转换到另一进程可覆盖current->thread.fpr(假定信号处理器用于floating-point指令)，可导致程序崩溃。 RedHat Enterprise Linux Desktop Workstation v. 5 client RedHat Enterprise Linux Desktop v.5 client RedHat Enterprise Linux v. 5 server Linux kernel 2.6.19 1 Linux kernel 2.6.19 .2 Linux kernel 2.6.19 .1 Linux kernel 2.6.19 -rc4 + Trustix Secure Enterprise Linux 2.0 + Trustix Secure Linux 2.2 + Trustix Secure Linux 2.1 + Trustix Secure Linux 2.0 Linux kernel 2.6.19 -rc3 + Trustix Secure Enterprise Linux 2.0 + Trustix Secure Linux 2.2 + Trustix Secure Linux 2.1 + Trustix Secure Linux 2.0 Linux kernel 2.6.19 -rc2 + Trustix Secure Enterprise Linux 2.0 + Trustix Secure Linux 2.2 + Trustix Secure Linux 2.1 + Trustix Secure Linux 2.0 Linux kernel 2.6.19...
