openSUSE Security Update : the Linux Kernel (openSUSE-2016-753)

critical Nessus Plugin ID 91736
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote openSUSE host is missing a security update.


The openSUSE Leap 42.1 kernel was updated to 4.1.26 to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2016-1583: Prevent the usage of mmap when the lower file system does not allow it. This could have lead to local privilege escalation when ecryptfs-utils was installed and /sbin/mount.ecryptfs_private was setuid (bsc#983143).

- CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface.

- CVE-2016-4805: Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. (bsc#980371).

- CVE-2016-4951: The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel did not verify socket existence, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation. (bsc#981058).

- CVE-2016-5244: An information leak vulnerability in function rds_inc_info_copy of file net/rds/recv.c was fixed that might have leaked kernel stack data.

- CVE-2016-4580: The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel did not properly initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.

- CVE-2016-0758: Tags with indefinite length could have corrupted pointers in asn1_find_indefinite_length (bsc#979867).

- CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bnc#963762).

- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bnc#955654).

- CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bnc#971126).

- CVE-2016-3672: The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel did not properly randomize the legacy base address, which made it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits (bnc#974308).

- CVE-2016-4482: A kernel information leak in the usbfs devio connectinfo was fixed, which could expose kernel stack memory to userspace. (bnc#978401).

- CVE-2016-4485: A kernel information leak in llc was fixed (bsc#978821).

- CVE-2016-4486: A kernel information leak in rtnetlink was fixed, where 4 uninitialized bytes could leak to userspace (bsc#978822).

- CVE-2016-4557: A use-after-free via double-fdput in replace_map_fd_with_map_ptr() was fixed, which could allow privilege escalation (bsc#979018).

- CVE-2016-4565: When the 'rdma_ucm' infiniband module is loaded, local attackers could escalate their privileges (bsc#979548).

- CVE-2016-4569: A kernel information leak in the ALSA timer via events via snd_timer_user_tinterrupt that could leak information to userspace was fixed (bsc#979213).

- CVE-2016-4578: A kernel information leak in the ALSA timer via events that could leak information to userspace was fixed (bsc#979879).

- CVE-2016-4581: If the first propogated mount copy was being a slave it could oops the kernel (bsc#979913)
