RedHat: Updated kernel packages fix security
Summary
Summary
The Linux kernel handles the basic functions of the operating system. This advisory includes fixes for the following security issues: iSEC Security Research discovered a VMA handling flaw in the uselib(2) system call of the Linux kernel. A local user could make use of this flaw to gain elevated (root) privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1235 to this issue. iSEC Security Research discovered a flaw in the page fault handler code that could lead to local users gaining elevated (root) privileges on multiprocessor machines. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0001 to this issue. iSEC Security Research and Georgi Guninski independently discovered a flaw in the scm_send function in the auxiliary message layer. A local user could create a carefully crafted auxiliary message which could cause a denial of service (system hang). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1016 to this issue. Kirill Korotaev found a flaw in load_elf_binary affecting kernels prior to 2.4.26. A local user could create a carefully crafted binary in such a way that it would cause a denial of service (system crash). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1234 to this issue. These packages also fix issues in the io_edgeport driver (CAN-2004-1017), a memory leak in ip_options_get (CAN-2004-1335), and missing VM_IO flags in some drivers (CAN-2004-1057). A recent Internet Draft by Fernando Gont recommended that ICMP Source Quench messages be ignored by hosts. A patch to ignore these messages is included. 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.
