Detail
Problem Description: Updated kernel packages that fix several security issues in the Red Hat Enterprise Linux 3 kernel are now available. This security advisory has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: The Linux kernel handles the basic functions of the operating system. These new kernel packages contain fixes for the security issues described below: * a flaw in the IPC shared-memory implementation that allowed a local user to cause a denial of service (deadlock) that resulted in freezing the system (CVE-2006-4342, Important) * an information leak in the copy_from_user() implementation on s390 and s390x platforms that allowed a local user to read arbitrary kernel memory (CVE-2006-5174, Important) * a flaw in the ATM subsystem affecting systems with installed ATM hardware and configured ATM support that allowed a remote user to cause a denial of service (panic) by accessing socket buffer memory after it has been freed (CVE-2006-4997, Moderate) * a directory traversal vulnerability in smbfs that allowed a local user to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences (CVE-2006-1864, Moderate) * a flaw in the mprotect system call that allowed enabling write permission for a read-only attachment of shared memory (CVE-2006-2071, Moderate) * a flaw in the DVD handling of the CDROM driver that could be used together with a custom built USB device to gain root privileges (CVE-2006-2935, Moderate) In addition to the security issues described above, a bug fix for a clock skew problem (which could lead to unintended keyboard repeat under X11) was also included. The problem only occurred when running the 32-bit x86 kernel on 64-bit dual-core x86_64 hardware. Note: The kernel-unsupported package contains various drivers and modules that are unsupported and therefore might contain security problems that have not been addressed. All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architecture and configurations as listed in this erratum. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/): 169428 - repetitive keystroke issue on both RH3 U5 32bit and RH4 U1 32bit. 189436 - CVE-2006-1864 smbfs chroot issue 190074 - CVE-2006-2071 mprotect gives write permission to a readonly attachment 197672 - CVE-2006-2935 Possible buffer overflow in DVD handling 205618 - CVE-2006-4342 shmat hangs by simultaneous shmctl(IPC_RMID) 206270 - CVE-2006-4997 IP over ATM clip_mkip dereference freed pointer 209436 - CVE-2006-5174 copy_from_user information leak on s390 |

The issue is triggered when a user attempts to change to a working directory outside a chroot environment in a SMBFS file system using a double backslash, e.g. 'cd ..\\'. It is possible that the flaw may allow unauthorised access to file system resources, resulting in a loss of confidentiality and/or integrity. |
