SuSE 11.1 Security Update : Linux kernel (SAT Patch Numbers 3760 / 3762 / 3763)

High Nessus Plugin ID 51614

Synopsis

The remote SuSE 11 host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.27 and fixes various bugs and security issues.

The following security issues were fixed :

- A local attacker could use a Oops (kernel crash) caused by other flaws to write a 0 byte to a attacker controlled address in the kernel. This could lead to privilege escalation together with other issues.
(CVE-2010-4258)

- A overflow in sendto() and recvfrom() routines was fixed that could be used by local attackers to potentially crash the kernel using some socket families like L2TP.
(CVE-2010-4160)

- A 32bit vs 64bit integer mismatch in gdth_ioctl_alloc could lead to memory corruption in the GDTH driver.
(CVE-2010-4157)

- The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel did not properly restrict TCP_MAXSEG (aka MSS) values, which allowed local users to cause a denial of service (OOPS) via a setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a signed integer. (CVE-2010-4165)

- A remote (or local) attacker communicating over X.25 could cause a kernel panic by attempting to negotiate malformed facilities. (CVE-2010-4164)

- A local attacker could cause memory overruns in the RDS protocol stack, potentially crashing the kernel. So far it is considered not to be exploitable. (CVE-2010-4175)

- Use-after-free vulnerability in mm/mprotect.c in the Linux kernel allwed local users to cause a denial of service via vectors involving an mprotect system call.
(CVE-2010-4169)

- A minor heap overflow in the CAN network module was fixed. Due to nature of the memory allocator it is likely not exploitable. (CVE-2010-3874)

- A memory information leak in berkely packet filter rules allowed local attackers to read uninitialized memory of the kernel stack. (CVE-2010-4158)

- A local denial of service in the blockdevice layer was fixed. (CVE-2010-4162)

- By submitting certain I/O requests with 0 length, a local user could have caused a kernel panic.
(CVE-2010-4163)

- The ethtool_get_rxnfc function in net/core/ethtool.c in the Linux kernel did not initialize a certain block of heap memory, which allowed local users to obtain potentially sensitive information via an ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt value. (CVE-2010-3861)

- arch/x86/kvm/x86.c in the Linux kernel did not initialize certain structure members, which allowed local users to obtain potentially sensitive information from kernel stack memory via read operations on the /dev/kvm device. (CVE-2010-3881)

- A range checking overflow in pktcdvd ioctl was fixed.
(CVE-2010-3437)

- The viafb_ioctl_get_viafb_info function in drivers/video/via/ioctl.c in the Linux kernel did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a VIAFB_GET_INFO ioctl call. (CVE-2010-4082)

- The ipc subsystem in the Linux kernel did not initialize certain structures, which allowed local users to obtain potentially sensitive information from kernel stack memory via vectors related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in ipc/compat_mq.c. (CVE-2010-4073)

- The copy_shmid_to_user function in ipc/shm.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the 'old shm interface.'. (CVE-2010-4072)

- The copy_semid_to_user function in ipc/sem.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via a (1) IPC_INFO, (2) SEM_INFO, (3) IPC_STAT, or (4) SEM_STAT command in a semctl system call. (CVE-2010-4083)

Solution

Apply SAT patch number 3760 / 3762 / 3763 as appropriate.
