Security update for the Linux Kernel
The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-1000251: The native Bluetooth stack was vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in remote code execution in kernel space (bnc#1057389).
- CVE-2017-14340: The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h did not verify that a filesystem has a realtime device, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory (bnc#1058524).
- CVE-2017-14140: The move_pages system call in mm/migrate.c did not check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR (bnc#1057179).
- CVE-2017-14051: An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c allowed local users to cause a denial of service (memory corruption and system crash) by leveraging root access (bnc#1056588).
- CVE-2017-10661: Race condition in fs/timerfd.c allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bnc#1053152).
- CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c a user-controlled buffer was copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow (bnc#1053148).
- CVE-2017-8831: The saa7164_bus_get function allowed local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a 'double fetch' vulnerability (bnc#1037994).
- CVE-2017-1000112: Prevent race condition in net-packet code that could have been exploited by unprivileged users to gain root access.(bnc#1052311).

Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, copy = maxfraglen - skb->len becomes negative on the non-UFO path and the branch to allocate new skb is taken. This triggers fragmentation and computation of fraggap = skb_prev->len - maxfraglen. Fraggap can exceed MTU, causing copy = datalen - transhdrlen - fraggap to become negative. Subsequently skb_copy_and_csum_bits() writes out-of-bounds. A similar issue is present in IPv6 code. The bug was introduced in e89e9cf539a2 ("[IPv4/IPv6]: UFO Scatter-gather approach") on Oct 18 2005.
