==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2009:0001-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0001.html Issue date: 2009-01-08 CVE Names: CVE-2006-4814 CVE-2007-2172 CVE-2007-3848 CVE-2007-4308 CVE-2007-6063 CVE-2007-6151 CVE-2007-6206 CVE-2008-0007 CVE-2008-2136 CVE-2008-3275 CVE-2008-3525 CVE-2008-4210 ==================================================================== 1. Summary: Updated kernel packages that fix a number of security issues are now available for Red Hat Enterprise Linux 2.1 running on 32-bit architectures. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. These updated packages fix the following security issues: * a flaw was found in the IPv4 forwarding base. This could allow a local, unprivileged user to cause a denial of service. (CVE-2007-2172, Important) * a flaw was found in the handling of process death signals. This allowed a local, unprivileged user to send arbitrary signals to the suid-process executed by that user. Successful exploitation of this flaw depends on the structure of the suid-program and its signal handling. (CVE-2007-3848, Important) * when accessing kernel memory locations, certain Linux kernel drivers registering a fault handler did not perform required range checks. A local, unprivileged user could use this flaw to gain read or write access to arbitrary kernel memory, or possibly cause a denial of service. (CVE-2008-0007, Important) * a possible kernel memory leak was found in the Linux kernel Simple Internet Transition (SIT) INET6 implementation. This could allow a local, unprivileged user to cause a denial of service. (CVE-2008-2136, Important) * missing capability checks were found in the SBNI WAN driver which could allow a local, unprivileged user to bypass intended capability restrictions. (CVE-2008-3525, Important) * a flaw was found in the way files were written using truncate() or ftruncate(). This could allow a local, unprivileged user to acquire the privileges of a different group and obtain access to sensitive information. (CVE-2008-4210, Important) * a race condition in the mincore system core allowed a local, unprivileged user to cause a denial of service. (CVE-2006-4814, Moderate) * a flaw was found in the aacraid SCSI driver. This allowed a local, unprivileged user to make ioctl calls to the driver which should otherwise be restricted to privileged users. (CVE-2007-4308, Moderate) * two buffer overflow flaws were found in the Integrated Services Digital Network (ISDN) subsystem. A local, unprivileged user could use these flaws to cause a denial of service. (CVE-2007-6063, CVE-2007-6151, Moderate) * a flaw was found in the way core dump files were created. If a local, unprivileged user could make a root-owned process dump a core file into a user-writable directory, the user could gain read access to that core file, potentially compromising sensitive information. (CVE-2007-6206, Moderate) * a deficiency was found in the Linux kernel virtual file system (VFS) implementation. This could allow a local, unprivileged user to attempt file creation within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate) All users of Red Hat Enterprise Linux 2.1 on 32-bit architectures should upgrade to these updated packages which address these vulnerabilities. For this update to take effect, the system must be rebooted. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at 5.
