Red Hat Linux Advisories: kernel, mozillaJul 21, 2003, 17:30 (0 Talkback[s])Red Hat Security Advisory
1. Topic: Updated kernel packages are now available fixing several security vulnerabilities. 2. Relevant releases/architectures: Red Hat Linux 7.1 - athlon, i386, i586, i686 3. Problem description: The Linux kernel handles the basic functions of the operating system. Several security issues have been discovered affecting the Linux kernel: CAN-2003-0461: /proc/tty/driver/serial reveals the exact character counts for serial links. This could be used by a local attacker to infer password lengths and inter-keystroke timings during password entry. CAN-2003-0462: Paul Starzetz discovered a file read race condition existing in the execve() system call, which could cause a local crash. CAN-2003-0464: A recent change in the RPC code set the reuse flag on newly-created sockets. Olaf Kirch noticed that his could allow normal users to bind to UDP ports used for services such as nfsd. CAN-2003-0476: The execve system call in Linux 2.4.x records the file descriptor of the executable process in the file table of the calling process, allowing local users to gain read access to restricted file descriptors. CAN-2003-0501: The /proc filesystem in Linux allows local users to obtain sensitive information by opening various entries in /proc/self before executing a setuid program. This causes the program to fail to change the ownership and permissions of already opened entries. CAN-2003-0550: The STP protocol is known to have no security, which could allow attackers to alter the bridge topology. STP is now turned off by default. CAN-2003-0551: STP input processing was lax in its length checking, which could lead to a denial of service. CAN-2003-0552: Jerry Kreuscher discovered that the Forwarding table could be spoofed by sending forged packets with bogus source addresses the same as the local host. All users are advised to upgrade to these errata packages, which contain backported security patches correcting these vulnerabilities. Important: If you use Red Hat Linux 7.1, you must have installed quota-3.06-9.71 from RHSA-2003-187, and if you use Red Hat Linux 7.2 or 7.3, you must have installed quota-3.06-9.7 from RHSA-2003-187. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To use Red Hat Network to upgrade the kernel, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. Note that you need to select the kernel explicitly if you are using the default configuration of up2date. To install kernel packages manually, use "rpm -ivh <package>" and modify system settings to boot the kernel you have installed. To do this, edit /boot/grub/grub.conf and change the default entry to "default=0" (or, if you have chosen to use LILO as your boot loader, edit /etc/lilo.conf and run lilo) Do not use "rpm -Uvh" as that will remove your running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5.

Updated Mozilla packages fixing various bugs and security issues are now available. [Updated 18 July 2003] 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 3. Problem description: Mozilla is an open source Web browser. A heap-based buffer overflow in Netscape and Mozilla allows remote attackers to execute arbitrary code via a jar: URL referencing a malformed .jar file, which overflows a buffer during decompression. This issue affects versions Mozilla packages for Red Hat Linux 7.1, 7.2, 7.3, and 8.0. These errata packages upgrade Mozilla to version 1.0.2, which is not vulnerable to this issue. Mozilla 1.0.2 also contains a number of other stability and security enhancements. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory only contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. RPMs required: Red Hat Linux 7.1: SRPMS: i386: Red Hat Linux 7.2: SRPMS: i386: Red Hat Linux 7.3: SRPMS: i386: Red Hat Linux 8.0: SRPMS: i386: 6.
