The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14089-1 advisory.

  - The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
    (CVE-2014-9710)

  - An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through     4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a     local attacker to exploit racy stack unwinding and leak kernel task stack contents. (CVE-2018-17972)

  - The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because     install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the     ptrace_may_access() check has a race condition when reading /proc/pid/stat. (CVE-2019-11190)

  - Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow     in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this     to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127,     4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff. (CVE-2019-11477)

  - Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux     kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote     attacker could use this to cause a denial of service. This has been fixed in stable kernel releases     4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit     f070ef2ac66716357066b683fb0baf55f8191a2e. (CVE-2019-11478)

  - Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a     remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote     attacker could use this to cause a denial of service. This has been fixed in stable kernel releases     4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits     967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363. (CVE-2019-11479)

  - The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has     multiple race conditions. (CVE-2019-11486)

  - The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a     local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command,     because a name field may not end with a '\0' character. (CVE-2019-11884)

  - The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers     to observe page cache access patterns of other processes on the same system, potentially allowing sniffing     of secret information. (Fixing this affects the output of the fincore program.) Limited remote     exploitation may be possible, as demonstrated by latency differences in accessing public files from an     Apache HTTP Server. (CVE-2019-5489)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
