NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2005-366.NASL description Updated kernel packages that fix several security issues are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. [Updated 9 August 2005] The advisory text has been updated to show that this update fixed the security issue named CVE-2005-0210 but not CVE-2005-0209. The issue CVE-2005-0209 was actually fixed by RHSA-2005:420. No changes have been made to the packages associated with this advisory. The Linux kernel handles the basic functions of the operating system. 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. (CVE-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). (CVE-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. (CVE-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. (CVE-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). (CVE-2005-0207) A small memory leak when defragmenting local packets was discovered that affected the Linux 2.6 kernel netfilter subsystem. A local user could send a large number of carefully crafted fragments leading to memory exhaustion (CVE-2005-0210) 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). (CVE-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. (CVE-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. (CVE-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). (CVE-2005-0529, CVE-2005-0530, CVE-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. (CVE-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). (CVE-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. (CVE-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. (CVE-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. (CVE-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. (CVE-2005-0839) Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

This allowed a remote attacker to crash the machine by sending specially crafted IP packet fragments. (CAN-2005-0209) The Netfilter code also contained a memory leak. Certain locally generated packet fragments are reassembled twice, which caused a double allocation of a data structure. This could be locally exploited to crash the machine due to kernel memory exhaustion. (CAN-2005-0210) Ben Martel and Stephen Blackheath found a remote Denial of Service vulnerability in the PPP driver. This allowed a malicious pppd client to crash the server machine. (CAN-2005-0384) Georgi Guninski discovered a buffer overflow in the ATM driver. The atm_get_addr() function does not validate its arguments sufficiently, which could allow a local attacker to overwrite large portions of kernel memory by supplying a negative length argument. This could eventually lead to arbitrary code execution. (CAN-2005-0531) Georgi Guninski also discovered three other integer comparison problems in the TTY layer, in the /proc interface and the ReiserFS driver. However, the previous Ubuntu security update (kernel version 2.6.8.1-16.11) already contained a patch which checks the arguments to these functions at a higher level and thus prevents these flaws from being exploited. (CAN-2005-0529, CAN-2005-0530, CAN-2005-0532) Georgi Guninski discovered an integer overflow in the sys_epoll_wait() function which allowed local users to overwrite the first few kB of physical memory. However, very few applications actually use this space (dosemu is a notable exception), but potentially this could lead to privilege escalation. (CAN-2005-0736) Eric Anholt discovered a race condition in the Radeon DRI driver. In some cases this allowed a local user with DRI privileges on a Radeon card to execute arbitrary code with root privileges. Finally this update fixes a regression in the NFS server driver which was introduced in the previous security update (kernel version 2.6.8.1-16.11). We apologize for the inconvenience.

This security advisory has been rated as having important security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. The following security issues were fixed : The Vicam USB driver did not use the copy_from_user function to access userspace, crossing security boundaries. (CVE-2004-0075) The ext3 and jfs code did not properly initialize journal descriptor blocks. A privileged local user could read portions of kernel memory. (CVE-2004-0177) The terminal layer did not properly lock line discipline changes or pending IO. An unprivileged local user could read portions of kernel memory, or cause a denial of service (system crash). (CVE-2004-0814) A race condition was discovered. Local users could use this flaw to read the environment variables of another process that is still spawning via /proc/.../cmdline. (CVE-2004-1058) A flaw in the execve() syscall handling was discovered, allowing a local user to read setuid ELF binaries that should otherwise be protected by standard permissions. (CVE-2004-1073). Red Hat originally reported this as being fixed by RHSA-2004:549, but the associated fix was missing from that update. Keith Owens reported a flaw in the Itanium unw_unwind_to_user() function.
