Detail

Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2007-3731

Evan Teran discovered a potential local denial of service (oops) in the handling of PTRACE_SETREGS and PTRACE_SINGLESTEP requests.

CVE-2007-3739

Adam Litke reported a potential local denial of service (oops) on powerpc platforms resulting from unchecked VMA expansion into address space reserved for hugetlb pages.

CVE-2007-3740

Steve French reported that CIFS filesystems with CAP_UNIX enabled were not honoring a process' umask which may lead to unintentinally relaxed permissions. CVE-2007-4573

Wojciech Purczynski discovered a vulnerability that can be exploitd by a local user to obtain superuser privileges on x86_64 systems. This resulted from improper clearing of the high bits of registers during ia32 system call emulation. This vulnerability is relevant to the Debian amd64 port as well as users of the i386 port who run the amd64 linux-image flavour.

CVE-2007-4849

Michael Stone reported an issue with the JFFS2 filesystem. Legacy modes for inodes that were created with POSIX ACL support enabled were not being written out to the medium, resulting in incorrect permissions upon remount.

These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-13etch3.

This advisory has been updated to include a build for the arm architecture, which was not yet available at the time of DSA-1378-1.

The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update:

Debian 4.0 (etch) fai-kernels 1.17+etch.13etch3 user-mode-linux 2.6.18-1um-2etch.13etch3

We recommend that you upgrade your kernel package immediately and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes.

Title: The Linux kernel 2.6.20 and 2.6.21 does not properly handle an invalid LDT segment selector in %cs (the xcs field) during ptrace single-step operations, which allows local users to cause a denial of service (NULL dereference and OOPS) via certain code that makes ptrace PTRACE_SETREGS and PTRACE_SINGLESTEP requests, related to the TRACE_IRQS_ON function, and possibly related to the arch_ptrace function.
