-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2008:0787-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0787.html Issue date: 2009-01-05 CVE Names: CVE-2007-3848 CVE-2006-4538 CVE-2006-4814 CVE-2007-4308 CVE-2007-2172 CVE-2007-6063 CVE-2007-6206 CVE-2007-6151 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 64-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 - ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 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 that allowed a local, unprivileged user to cause an out-of-bounds access. (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 depended 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 kernel crash. (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 flaw was found in the ELF handling on Itanium-based systems. This triggered a cross-region memory-mapping and allowed a local, unprivileged user to cause a local denial of service. (CVE-2006-4538, Moderate) * a race condition in the mincore system core allowed a local, unprivileged user to cause a local denial of service (system hang). (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 local denial of service. (CVE-2008-3275, Moderate) All users of Red Hat Enterprise Linux 2.1 on 64-bit architectures should upgrade to these updated packages, which contain backported patches to resolve these issues. 4.
