kernel: hfs buffer overflow

Stack-based buffer overflow in the hfs subsystem in the Linux kernel 2.6.32 allows remote attackers to have an unspecified impact via a crafted Hierarchical File System HFS filesystem, related to the hfsreaddir function in fs/hfs/dir.c...

openSUSE Security Update : kernel (kernel-1749)

The openSUSE 11.1 Kernel was updated to 2.6.27.42 fixing various bugs and security issues. Following security issues were fixed: CVE-2009-4536: A underflow in the e1000 jumbo ethernet frame handling could be use by link-local remote attackers to crash the machine or potentially execute code in...

Linux Kernel HFS子系统栈溢出漏洞

CVE ID: CVE-2009-4020 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的fs/hfs/dir.c文件中的hfsreaddir函数存在栈溢出漏洞，特制的多级文件系统（HFS）可以在 hfsbnoderead函数的memcpy调用过程中触发这个溢出。攻击者可以提供源缓冲区和长度，目标缓冲区是固定长度的本地变量，这个变量存储在了hfsbnoderead调用程序的栈帧中（hfsreaddir）。由于在试图读取文件系统上目录时都会执行 hfsreaddir函数，因此用户试图检查任何文件系统内容时都会调用这个函数。 Linux...

CVE-2009-4020

CVE-2009-4020 describes a stack-based buffer overflow in the Linux kernel 2.6.32 hfs subsystem (fs/hfs/dir.c, hfs_readdir). A crafted Hierarchical File System (HFS) filesystem could allow an attacker to achieve an unspecified impact via the HFS filesystem. Several Nessus/GD advisories link this C...

Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : linux, linux-source-2.6.15/22 vulnerabilities (USN-679-1)

It was discovered that the Xen hypervisor block driver did not correctly validate requests. A user with root privileges in a guest OS could make a malicious IO request with a large number of blocks that would crash the host OS, leading to a denial of service. This only affected Ubuntu 7.10...

Race condition

Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service kernel memory corruption by simultaneously executing the same HFSSETPKGEXTENSIONS code path in multiple threads, which is problematic...

Design/Logic Flaw

XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving...

CVE-2009-1238

The CVE relates to a race condition in the HFS vfs sysctl interface of the XNU kernel (affected: older Apple Mac OS X 10.5.6 and earlier; specific build 1228.8.20 and earlier). The flaw arises from lack of mutex locking for an unspecified global variable, allowing local users to trigger kernel me...
