This is a major release which culminates many months of development and testing, and incorporates the latest in open source technology. "Ceara" features: The Linux 2.6.11 kernel, grsecurity support, APT for advanced package management, the next generation PHP 5 environment (5.0.3), high availability features such as DRBD (0.7.10) and UCARP (1.1), the latest development tools and languages (gcc 3.4.3, Python 2.4), and much more. tinysofa classic server may be downloaded from: http://classic.tinysofa.org/download/ -- Jaakko From security at tinysofa.org Thu Apr 21 19:11:22 2005 From: security at tinysofa.org (tinysofa Security Team) Date: Thu, 21 Apr 2005 15:11:22 -0400 Subject: [tinysofa-announce] TSSA-2005-021-ES - kernel Message-ID: <20050421191122.GA15043@minbar.tinysofa.org> =========================================================================== _ |_ . _ _ _ (_ _ |_ | | ) \/ _) (_) | (_| / Security Advisory #2005-021-ES Package name: kernel Summary: Multiple security fixes Advisory ID: TSSA-2005-021-ES Date: 2005-04-22 Affected versions: tinysofa enterprise server 2.0 CVE names: CAN-2005-0135 CAN-2005-0207 CAN-2005-0209 CAN-2005-0384 CAN-2005-0400 CAN-2005-0449 CAN-2005-0529 CAN-2005-0530 CAN-2005-0531 CAN-2005-0736 CAN-2005-0749 CAN-2005-0750 CAN-2005-0767 CAN-2005-0815 CAN-2005-0839 CAN-2005-0867 CAN-2005-0977 CAN-2005-1041 =========================================================================== Security Fixes ============== Description ----------- kernel: * Linux [0] is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. Issues resolved: A flaw in the fib_seq_start function was discovered. A local user could use this flaw to cause a denial of service (system crash) via /proc/net/route. (CAN-2005-1041) A flaw in the tmpfs file system was discovered. A local user could use this flaw to cause a denial of service (system crash). (CAN-2005-0977) An integer overflow flaw was found when writing to a sysfs file. A local user could use this flaw to overwrite kernel memory, causing a denial of service (system crash) or arbitrary code execution. (CAN-2005-0867) Keith Owens reported a flaw in the Itanium unw_unwind_to_user function. A local user could use this flaw to cause a denial of service (system crash) on Itanium architectures. (CAN-2005-0135) A flaw in the NFS client O_DIRECT error case handling was discovered. A local user could use this flaw to cause a denial of service (system crash). (CAN-2005-0207) A flaw in fragment forwarding was discovered that affected the netfilter subsystem for certain network interface cards. A remote attacker could send a set of bad fragments and cause a denial of service (system crash). Acenic and SunGEM network interfaces were the only adapters affected, which are in widespread use. (CAN-2005-0209) A flaw was discovered in the Linux PPP driver. On systems allowing remote users to connect to a server using ppp, a remote client could cause a denial of service (system crash). (CAN-2005-0384) A flaw was discovered in the ext2 file system code. When a new directory is created, the ext2 block written to disk is not initialized, which could lead to an information leak if a disk image is made available to unprivileged users. (CAN-2005-0400) A flaw in fragment queuing was discovered that affected the Linux kernel netfilter subsystem. On systems configured to filter or process network packets (e.g. firewalling), a remote attacker could send a carefully crafted set of fragmented packets to a machine and cause a denial of service (system crash). In order to sucessfully exploit this flaw, the attacker would need to know or guess some aspects of the firewall ruleset on the target system. (CAN-2005-0449) A number of flaws were found in the Linux 2.6 kernel. A local user could use these flaws to read kernel memory or cause a denial of service (crash). (CAN-2005-0529, CAN-2005-0530, CAN-2005-0531) An integer overflow in sys_epoll_wait in eventpoll.c was discovered. A local user could use this flaw to overwrite low kernel memory. This memory is usually unused, not usually resulting in a security consequence. (CAN-2005-0736) A flaw when freeing a pointer in load_elf_library was discovered. A local user could potentially use this flaw to cause a denial of service (crash). (CAN-2005-0749) A flaw was discovered in the bluetooth driver system. On systems where the bluetooth modules are loaded, a local user could use this flaw to gain elevated (root) privileges. (CAN-2005-0750) A race condition was discovered that affected the Radeon DRI driver. A local user who has DRI privileges on a Radeon graphics card may be able to use this flaw to gain root privileges. (CAN-2005-0767) Multiple range checking flaws were discovered in the iso9660 file system handler. An attacker could create a malicious file system image which would cause a denial or service or potentially execute arbitrary code if mounted. (CAN-2005-0815) A flaw was discovered when setting line discipline on a serial tty. A local user may be able to use this flaw to inject mouse movements or keystrokes when another user is logged in. (CAN-2005-0839) References ---------- [0] http://www.kernel.org/ Recommended Action ================== We recommend that all systems be upgraded as soon as possible. Location ======== All tinysofa updates are available from Automatic Updates ================= Users of the APT tool can enjoy having updates automatically installed using 'apt-get dist-upgrade'. Please make sure that the new kernel is set as the default kernel in /etc/grub.conf before rebooting. This can be achieved by changing the 'default=' line to match the correct position of the new kernel (which should be '0'.)
