Linux Kernel EFI分区拒绝服务漏洞

Bugtraq ID: 47343 Linux是一款开放源代码的操作系统。 不管是否启用了自动安装，Linux内核会自动评测存储设备的分区表。评测EFI GUID分区表存在一个缓冲区溢出，可导致内核触发oops而崩溃。 Linux kernel 2.6.38 Linux kernel 2.6.37 Linux kernel 2.6.37 Linux kernel 2.6.36 Linux kernel 2.6.35 Linux kernel 2.6.35 Linux kernel 2.6.35 Linux kernel 2.6.34 Linux kernel 2.6.34 Linux...

Design/Logic Flaw

The ldmparsevmdb function in fs/partitions/ldm.c in the Linux kernel before 2.6.38-rc6-git6 does not validate the VBLK size value in the VMDB structure in an LDM partition table, which allows local users to cause a denial of service divide-by-zero error and OOPS via a crafted partition table...

CVE-2011-1012

CVE-2011-1012 affects the Linux kernel, in particular the LDM partition handling. The flaw lies in ldm_parse_vmdb in fs/partitions/ldm.c, which does not validate the VBLK size in the VMDB structure of an LDM partition table. A crafted partition table can trigger a divide-by-zero and cause a kerne...

CVE-2010-4342

Vulnerability (CVE-2010-4342) in the Linux kernel affects the AUN path when Econet is enabled. The flaw is in the aun_incoming function (net/econet/af_econet.c) and allows remote attackers to trigger a NULL pointer dereference and kernel OOPS, causing a denial of service via UDP-based Acorn Unive...

CVE-2010-3849

CVE-2010-3849 affects the Linux kernel’s econet_sendmsg path (net/econet/af_econet.c) prior to 2.6.36.2, when an Econet address is configured. A local user can trigger a denial of service by issuing a sendmsg with a NULL remote address, causing a NULL pointer dereference and OOPS. The correspondi...

CVE-2010-4165

CVE-2010-4165 affects the Linux kernel prior to 2.6.37-rc2. The do_tcp_setsockopt function does not properly constrain TCP_MAXSEG (MSS) values, allowing a local user to trigger a denial of service via a setsockopt with a small value, leading to a divide-by-zero or signed-integer misuse. Evidence ...

Null pointer dereference

The pppol2tpxmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel before 2.6.34 does not properly validate certain values associated with an interface, which allows attackers to cause a denial of service NULL pointer dereference and OOPS or possibly have unspecifi...

CVE-2010-2495

CVE-2010-2495 affects the Linux kernel’s L2TP implementation (pppol2tp.c). The vulnerability arises from improper validation of certain interface-related values in pppol2tp_xmit, enabling a NULL pointer dereference and an OOPs that can cause a denial of service via routing-change vectors. The iss...
