Linux Kernel copy_from_user_mmap_sem()函数内存访问漏洞

BUGTRAQ ID: 27796 CVECAN ID: CVE-2008-0010 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的实现上存在漏洞，本地攻击者可能利用此漏洞获取内核内存的敏感信息。 Linux Kernel的fs/splice.c文件中的copyfromusermmapsem函数未经验证用户提供的指针便使用copyfromuserinatomic拷贝了用户进程内存中的数据： ---8--- fs/splice.c:1188 ---8--- partial = copyfromuserinatomicdst, src, n;...

Null pointer dereference

The copyfromusermmapsem function in fs/splice.c in the Linux kernel 2.6.22 through 2.6.24 does not validate a certain userspace pointer before dereference, which allow local users to read from arbitrary kernel memory locations...

CVE-2008-0009

The CVE-2008-0009 entry is supported by connected documents: it affects Linux kernel 2.6.22–2.6.24 where vmsplice_to_user dereferences a userspace pointer without validation, enabling local access to kernel memory. The issue is a local privilege‑escalation vulnerability; remediation is associated...

Sun Solaris I_PEEK IOCTL处理器信息泄露漏洞

Sun Solaris是一款商业性质的操作系统。 Sun Solaris IPEEK IOCTL处理器存在整数无符号错误，本地攻击者可以利用漏洞获得内存敏感信息。 Sun Solaris内核提供的FIFO FS先进先出文件系统服务用于IPC通信，一个FIFO代表文件系统中的节点类似windows系统中的有名管道概念。 kernel FIFOs ioctl处理器存在漏洞，IPEEK ioctl用于进程查看包含在FIFO中的字节数，而实际该操作并清除队列中的消息。这个命令的其中一个参数代表要取数的字节数，是符号整数值，由于这个参数没有正确验证，提供负值可导致内核内存内容被泄露。 Sun...
