SuSE 10 Security Update : the Linux kernel (ZYPP Patch Number 6237)
high Nessus Plugin ID 41539
Synopsis
The remote SuSE 10 host is missing a security-related patch.Description
The Linux kernel on SUSE Linux Enterprise 10 Service Pack 2 was updated to fix various security issues and several bugs.The following security issues were fixed: CVE-2009-0834: The audit_syscall_entry function in the Linux kernel on the x86_64 platform did not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls.
- nfsd in the Linux kernel did not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option. (CVE-2009-1072)
- The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod. (CVE-2009-0835)
- Buffer overflow in fs/cifs/connect.c in CIFS in the Linux kernel 2.6.29 and earlier allows remote attackers to cause a denial of service (crash) or potential code execution via a long nativeFileSystem field in a Tree Connect response to an SMB mount request.
(CVE-2009-1439)
This requires that kernel can be made to mount a 'cifs' filesystem from a malicious CIFS server.
- The exit_notify function in kernel/exit.c in the Linux kernel did not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.
(CVE-2009-1337)
- The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program. (SUSE is enabling CONFIG_SHMEM, so is by default not affected, the fix is just for completeness). (CVE-2009-0859)
The GCC option -fwrapv has been added to compilation to work around potentially removing integer overflow checks.
- Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel might allow attackers to obtain sensitive information via a large length value, which causes 'garbage' memory to be sent. (CVE-2009-1265)
Also a number of bugs were fixed, for details please see the RPM changelog.
