Detail

Notice: Debian 5.0.4, the next point release of Debian 'lenny', will include a new default value for the mmap_min_addr tunable. This change will add an additional safeguard against a class of security vulnerabilities known as "NULL pointer dereference" vulnerabilities, but it will need to be overridden when using certain applications. Additional information about this change, including instructions for making this change locally in advance of 5.0.4 (recommended), can be found at: http://wiki.debian.org/mmap_min_addr

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2009-2695

Eric Paris provided several fixes to increase the protection provided by the mmap_min_addr tunable against NULL pointer dereference vulnerabilities.

CVE-2009-2903

Mark Smith discovered a memory leak in the appletalk implementation. When the appletalk and ipddp modules are loaded, but no ipddp"N" device is found, remote attackers can cause a denial of service by consuming large amounts of system memory.

CVE-2009-2908

Loic Minier discovered an issue in the eCryptfs filesystem. A local user can cause a denial of service (kernel oops) by causing a dentry value to go negative.

CVE-2009-2909

Arjan van de Ven discovered an issue in the AX.25 protocol implementation. A specially crafted call to setsockopt() can result in a denial of service (kernel oops).

CVE-2009-2910

Jan Beulich discovered the existence of a sensitive kernel memory leak. Systems running the 'amd64' kernel do not properly sanitize registers for 32-bit processes.

CVE-2009-3001

Jiri Slaby fixed a sensitive memory leak issue in the ANSI/IEEE 802.2 LLC implementation. This is not exploitable in the Debian lenny kernel as root privileges are required to exploit this issue.

CVE-2009-3002

Eric Dumazet fixed several sensitive memory leaks in the IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and Controller Area Network (CAN) implementations. Local users can exploit these issues to gain access to kernel memory.

CVE-2009-3286

Eric Paris discovered an issue with the NFSv4 server implementation. When an O_EXCL create fails, files may be left with corrupted permissions, possibly granting unintentional privileges to other local users.

CVE-2009-3290

Jan Kiszka noticed that the kvm_emulate_hypercall function in KVM does not prevent access to MMU hypercalls from ring 0, which allows local guest OS users to cause a denial of service (guest kernel crash) and read or write guest kernel memory.

CVE-2009-3613

Alistair Strachan reported an issue in the r8169 driver. Remote users can cause a denial of service (IOMMU space exhaustion and system crash) by transmitting a large amount of jumbo frames.

For the stable distribution (lenny), this problem has been fixed in version 2.6.26-19lenny1.

For the oldstable distribution (etch), these problems, where applicable, will be fixed in updates to linux-2.6 and linux-2.6.24.

We recommend that you upgrade your linux-2.6 and user-mode-linux packages.

Note: Debian carefully tracks all known security issues across every linux kernel package in all releases under active security support. However, given the high frequency at which low-severity security issues are discovered in the kernel and the resource requirements of doing an update, updates for lower priority issues will normally not be released for all kernels at the same time. Rather, they will be released in a staggered or "leap-frog" fashion.

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

Title: DSA-1907-1 kvm -- several vulnerabilities
Description: Several vulnerabilities have been discovered in kvm, a full virtualization system. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2008-5714 Chris Webb discovered an off-by-one bug limiting KVM's VNC passwords to 7 characters. This flaw might make it easier for remote attackers to guess the VNC password, which is limited to seven characters where eight was intended. CVE-2009-3290 It was discovered that the kvm_emulate_hypercall function in KVM does not prevent access to MMU hypercalls from ring 0, which allows local guest OS users to cause a denial of service and read or write guest kernel memory. For the stable distribution, these problems have been fixed in version 72+dfsg-5~lenny3. The oldstable distribution does not contain kvm. For the testing distribution these problems will be fixed soon. For the unstable distribution these problems have been fixed in version 85+dfsg-4.1 We recommend that you upgrade your kvm packages.

Title: NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL 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 do_open_permission function even when a create fails.

Title: The Linux kernel before 2.6.31-rc7 does not properly prevent mmap operations that target page zero and other low memory addresses, which allows local users to gain privileges by exploiting NULL pointer dereference vulnerabilities, related to (1) the default configuration of the allow_unconfined_mmap_low boolean in SELinux on Red Hat Enterprise Linux (RHEL) 5, (2) an error that causes allow_unconfined_mmap_low to be ignored in the unconfined_t domain, (3) lack of a requirement for the CAP_SYS_RAWIO capability for these mmap operations, and (4) interaction between the mmap_min_addr protection mechanism and certain application programs.

Linux Kernel Driver r8169 contains a flaw that may allow a remote denial of service. The issue is triggered when an error in the 'swiotlb' functionality in the r8169 driver in drivers/net/r8169.c in the Linux kernel occurs and will allow remote and local attackers to cause a denial or service attack that results in IOMMU space exhaustion and system crash by using jumbo frames for a large amount of network traffic, and will result in loss of availability for the platform.
