Vulnerability Title
N/A
Vulnerability Description
The Linux kernel before 2.6.31-rc7 does not properly prevent mmap operations that target page zero and other low memory addresses, which allows local users to gain privileges by exploiting NULL pointer dereference vulnerabilities, related to (1) the default configuration of the allow_unconfined_mmap_low boolean in SELinux on Red Hat Enterprise Linux (RHEL) 5, (2) an error that causes allow_unconfined_mmap_low to be ignored in the unconfined_t domain, (3) lack of a requirement for the CAP_SYS_RAWIO capability for these mmap operations, and (4) interaction between the mmap_min_addr protection mechanism and certain application programs.

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。 Red Hat Enterprise Linux 5.3的selinux-policy软件包提供了SELinux布尔值allow_unconfined_mmap_low，用于控制是否对在不受限制域(如unconfined_t或initrc_t)中所运行的进程应用mmap_min_addr限制。但allow_unconfined_mmap_low布
