OVERVIEW - -------- This update fixes several vulnerabilities in the Linux kernel. CAN-2002-1380 ------------- Local users could cause a denial of service by using the mmap() function with the PROT_READ parameter to access memory pages via the /proc/pid/mem interface. CAN-2003-0001 ------------- Most of the Ethernet card (NIC) device drivers did not pad frames with null bytes, leading to the potential leakage of kernel memory. CAN-2003-0127 ------------- There is a vulnerability in the kernel module loader which could allow a local attacker to obtain root privileges by using ptrace to attach to a child process spawned by the kernel when a new module is loaded. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2002-1380, CAN-2003-0001, and CAN-2003-0127 to these issues. All users are recommended to upgrade immediately using the special SOLUTION in this advisory. SOLUTION - -------- Users of the EnGarde Professional edition can use the Guardian Digital Secure Network to update their systems automatically. EnGarde Community users should upgrade to the most recent version as outlined in this advisory. Updates may be obtained from: ftp://ftp.engardelinux.org/pub/engarde/stable/updates/ http://ftp.engardelinux.org/pub/engarde/stable/updates/ Please read and understand this entire section before you attempt to upgrade the kernel. Initial Steps ------------- 1) Verify the machine is either: a) booted into a "standard" kernel; or b) LIDS is disabled (/sbin/lidsadm -S -- -LIDS_GLOBAL) 2) Determine which kernels you currently have installed: # rpm -qa --qf "%{NAME}\n" | grep kernel 3) Download the new kernels that match what you have installed (based on step 2) from the "UPDATED PACKAGES" section of this advisory. Installation Steps ------------------ 4) Install the new packages. The packages will automagically update /etc/lilo.conf by commenting out any old EnGarde images and replacing them with the new ones: # rpm --replacefiles -i kernel1 kernel2 ... 5) Re-run LILO. If you see any errors then open /etc/lilo.conf in your favorite text editor and make the appropriate changes: # /sbin/lilo Final Steps ----------- 6) If you did not see any LILO errors then your new kernel is now installed and your machine is ready to be rebooted: # reboot UPDATED PACKAGES - ---------------- These updated packages are for EnGarde Secure Linux Community Edition.
