RedHat: Important: kernel security update RHSA-2006:0190-01
Summary
Summary
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 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 exec() handling on some 64-bit architectures that allowed a local user to cause a denial of service (crash) (CVE-2005-2708, important) - - 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 race condition affecting SMP systems that allowed a local user to cause a denial of service (crash) (CVE-2005-3274, 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 - - Correct scsi error return 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.
