Linux Kernel "fs/partitions/ldm.c"缓冲区溢出和拒绝服务漏洞

BUGTRAQ ID: 46512 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的"fs/partitions/ldm.c"在实现上存在缓冲区溢出和拒绝服务漏洞，攻击者可利用此漏洞执行任意代码、提升权限、泄露敏感信息和造成拒绝服务。 不管是否启用了自动分区，Kernel自动评估存储设备分区表。评估MAC和LDM分区表的代码包含下列漏洞： 1、fs/partitions/mac.c中的macpartition存在缓冲区溢出漏洞导致通过破坏的MAC分区表造成拒绝服务。...

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...
