Updated kernel packages that fix a number of security issues as well as other bugs are now available for Red Hat Enterprise Linux 2.1 (32 bit architectures)

This security advisory has been rated as having important security impact by the Red Hat Security Response Team.

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 network IGMP processing that a allowed a     remote user on the local network to cause a denial of     service (disabling of multicast reports) if the system     is running multicast applications (CVE-2002-2185,     moderate)

  - a race condition that allowed local users to read the     environment variables of another process (CVE-2004-1058,     low)

  - a flaw in the open_exec function of execve that allowed     a local user to read setuid ELF binaries that should     otherwise be protected by standard permissions.
    (CVE-2004-1073, moderate). Red Hat originally reported     this flaw as being fixed by RHSA-2004:504, but a patch     for this issue was missing from that update.

  - a flaw in the coda module that allowed a local user to     cause a denial of service (crash) or possibly gain     privileges (CVE-2005-0124, moderate)

  - a potential leak of kernel data from ext2 file system     handling (CVE-2005-0400, low)

  - flaws in ISO-9660 file system handling that allowed the     mounting of an invalid image on a CD-ROM to cause a     denial of service (crash) or potentially execute     arbitrary code (CVE-2005-0815, moderate)

  - a flaw in gzip/zlib handling internal to the kernel that     may allow a local user to cause a denial of service     (crash) (CVE-2005-2458, low)

  - a flaw in procfs handling during unloading of modules     that allowed a local user to cause a denial of service     or potentially gain privileges (CVE-2005-2709, moderate)

  - a flaw in IPv6 network UDP port hash table lookups that     allowed a local user to cause a denial of service (hang)     (CVE-2005-2973, important)

  - a network buffer info leak using the orinoco driver that     allowed a remote user to possibly view uninitialized     data (CVE-2005-3180, important)

  - a flaw in IPv4 network TCP and UDP netfilter handling     that allowed a local user to cause a denial of service     (crash) (CVE-2005-3275, important)

  - a flaw in the IPv6 flowlabel code that allowed a local     user to cause a denial of service (crash)     (CVE-2005-3806, important)

The following bugs were also addressed :

  - Handle set_brk() errors in binfmt_elf/aout

  - Correct error handling in shmem_ioctl

  - Correct scsi error return

  - Fix netdump time keeping bug

  - Fix netdump link-down freeze

  - Fix FAT fs deadlock

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

Updated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 3. This is the sixth regular update.

This security advisory has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

This is the sixth regular kernel update to Red Hat Enterprise Linux 3.

New features introduced by this update include :

  - diskdump support on HP Smart Array devices -     netconsole/netdump support over bonded interfaces - new     chipset and device support via PCI table updates -     support for new 'oom-kill' and 'kscand_work_percent'     sysctls - support for dual core processors and ACPI     Power Management timers on AMD64 and Intel EM64T systems

There were many bug fixes in various parts of the kernel. The ongoing effort to resolve these problems has resulted in a marked improvement in the reliability and scalability of Red Hat Enterprise Linux 3.

There were numerous driver updates and security fixes (elaborated below). Other key areas affected by fixes in this update include kswapd, inode handling, the SATA subsystem, diskdump handling, ptrace() syscall support, and signal handling.

The following device drivers have been upgraded to new versions :

3w-9xxx ---- 2.24.03.008RH cciss ------ 2.4.58.RH1 e100 ------- 3.4.8-k2 e1000 ------ 6.0.54-k2 emulex ----- 7.3.2 fusion ----- 2.06.16i.01 iscsi ------ 3.6.2.1 ipmi ------- 35.4 lpfcdfc ---- 1.2.1 qlogic ----- 7.05.00-RH1 tg3 -------- 3.27RH

The following security bugs were fixed in this update :

  - a flaw in syscall argument checking on Itanium systems     that allowed a local user to cause a denial of service     (crash) (CVE-2005-0136)

  - a flaw in stack expansion that allowed a local user of     mlockall() to cause a denial of service (memory     exhaustion) (CVE-2005-0179)

  - a small memory leak in network packet defragmenting that     allowed a remote user to cause a denial of service     (memory exhaustion) on systems using netfilter     (CVE-2005-0210)

  - flaws in ptrace() syscall handling on AMD64 and Intel     EM64T systems that allowed a local user to cause a     denial of service (crash) (CVE-2005-0756, CVE-2005-1762,     CVE-2005-2553)

  - flaws in ISO-9660 file system handling that allowed the     mounting of an invalid image on a CD-ROM to cause a     denial of service (crash) or potentially execute     arbitrary code (CVE-2005-0815)

  - a flaw in ptrace() syscall handling on Itanium systems     that allowed a local user to cause a denial of service     (crash) (CVE-2005-1761)

  - a flaw in the alternate stack switching on AMD64 and     Intel EM64T systems that allowed a local user to cause a     denial of service (crash) (CVE-2005-1767)

  - race conditions in the ia32-compat support for exec()     syscalls on AMD64, Intel EM64T, and Itanium systems that     could allow a local user to cause a denial of service     (crash) (CVE-2005-1768)

  - flaws in IPSEC network handling that allowed a local     user to cause a denial of service or potentially gain     privileges (CVE-2005-2456, CVE-2005-2555)

  - a flaw in sendmsg() syscall handling on 64-bit systems     that allowed a local user to cause a denial of service     or potentially gain privileges (CVE-2005-2490)

  - flaws in unsupported modules that allowed     denial-of-service attacks (crashes) or local privilege     escalations on systems using the drm, coda, or moxa     modules (CVE-2004-1056, CVE-2005-0124, CVE-2005-0504)

  - potential leaks of kernel data from jfs and ext2 file     system handling (CVE-2004-0181, CVE-2005-0400)

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 architectures and configurations as listed in this erratum.

The remote CentOS system is missing a security update which has been documented in Red Hat advisory RHSA-2005-663.
