kernel: security and bugfix update (important)

The Linux kernel was updated to fix various bugs and security issues: CVE-2013-0871: Race condition in the ptrace functionality in the Linux kernel allowed local users to gain privileges via a PTRACESETREGS ptrace system call in a crafted application, as demonstrated by ptracedeath. CVE-2013-0160...

CVE-2012-3375

The epollctl system call in fs/eventpoll.c in the Linux kernel before 3.2.24 does not properly handle ELOOP errors in EPOLLCTLADD operations, which allows local users to cause a denial of service file-descriptor consumption and system crash via a crafted application that attempts to create a...

CVE-2012-3375

CVE-2012-3375—Linux kernel epoll_ctl DoS Affected: Linux kernel before 3.2.24 (fs/eventpoll.c).Cause: EPOLL_CTL_ADD mishandles ELOOP errors, due to an incorrect fix for CVE-2011-1083.Impact: Local users can trigger a denial of service via a crafted application that creates circular epoll dependen...

kernel: excessive in kernel CPU consumption when creating large nested epoll structures

The epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service CPU consumption via a crafted application that makes epollcreate and epollctl system calls...

Linux Kernel epoll Subsystem “eventpoll.c”多个本地拒绝服务漏洞

BUGTRAQ ID: 46630 CVE ID: CVE-2011-1082,CVE-2011-1083 Linux Kernel是Linux操作系统的内核。 Linux Kernel 2.6.38之前版本的fs/eventpoll.c在epoll子系统的实现上存在本地拒绝服务安全漏洞，将epoll文件描述符放置在其他epoll数据结构中，没有检查已关闭的循环或深链接，攻击者可利用此漏洞造成拒绝服务 0 Linux kernel 2.6.38 厂商补丁： Linux ----- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： http://www.kernel.or...

kernel: potential kernel deadlock when creating circular epoll file structures

fs/eventpoll.c in the Linux kernel before 2.6.38 places epoll file descriptors within other epoll data structures without properly checking for 1 closed loops or 2 deep chains, which allows local users to cause a denial of service deadlock or stack memory consumption via a crafted application tha...
