Mandriva Linux Security Advisory : kernel (MDVSA-2009:148)

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel : Buffer overflow in the RTL8169 NIC driver drivers/net/r8169.c in the Linux kernel before 2.6.30 allows remote attackers to cause a denial of service kernel memory corruption and crash via a long packet. CVE-2009-1389 The...

CVE-2003-1575

VERITAS File System VxFS 3.3.3, 3.4, and 3.5 before MP1 Rolling Patch 02 for Sun Solaris 2.5.1 through 9 does not properly implement inheritance of default ACLs in certain circumstances related to the characteristics of a directory inode, which allows local users to bypass intended file permissio...

kernel: O_EXCL creates on NFSv4 are broken

NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an OEXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the...

Linux Kernel 2.6.x - 'pipe.c' Local Privilege Escalation (2)

/ source: https://www.securityfocus.com/bid/36901/info Linux kernel is prone to a local privilege-escalation vulnerability that is caused by a NULL-pointer dereference. Local attackers can exploit this issue to execute arbitrary code with kernel-level privileges. Successful exploits will result i...

Linux Kernel O_EXCL NFSv4本地权限提升漏洞

BUGTRAQ ID: 36472 CVE ID: CVE-2009-3286 Linux Kernel是开放源码操作系统Linux所使用的内核。 当OEXCL创建文件失败时，Linux Kernel的NFSv4没有正确地清除inode。这导致以不安全的设置（如setuid位）创建文件，本地用户可以通过执行doopenpermission函数获得权限提升。 Linux kernel 2.6.x 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://git.kernel.org/linus/af85852d...
