(bsc#1137586).\n\n- CVE-2019-11478: It was possible to send a crafted sequence of SACKs which\n  would fragment the TCP retransmission queue. A remote attacker may have been \n  able to further exploit the fragmented queue to cause an expensive linked-list\n  walk for subsequent SACKs received for that same TCP connection.\n\n- CVE-2019-11479: It was possible to send a crafted sequence of SACKs which\n  would fragment the RACK send map. A remote attacker may have been able to further\n  exploit the fragmented send map to cause an expensive linked-list walk for\n  subsequent SACKs received for that same TCP connection. This would have\n  resulted in excess resource consumption due to low mss values.\n\n- CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly\n  escalate privileges was found in the mwifiex kernel module while connecting\n  to a malicious wireless network. (bnc#1136424)\n\n- CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux\n  kernel allowed local attackers to observe page cache access patterns of other\n  processes on the same system, potentially allowing sniffing of secret\n  information. (Fixing this affects the output of the fincore program.) Limited\n  remote exploitation may have been possible, as demonstrated by latency differences\n  in accessing public files from an Apache HTTP Server. (bnc#1120843)\n\n- CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the\n  unused memory region in the extent tree block, which might have allowed local users\n  to obtain sensitive information by reading uninitialized data in the\n  filesystem. (bnc#1135281)\n\n- CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on setuid\n  programs (such as /bin/su) because install_exec_creds() is called too late in\n  load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check\n  has a race condition when reading /proc/pid/stat. (bnc#1131543)\n\n- CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c\n  in the Linux kernel allowed a local user to obtain potentially sensitive\n  information from kernel stack memory via a HIDPCONNADD command, because a\n  name field may not end with a '\\0' character. (bnc#1134848)\n\n- CVE-2018-17972: An issue was discovered in the proc_pid_stack function in\n  fs/proc/base.c in the Linux kernel It did not ensure that only root may\n  inspect the kernel stack of an arbitrary task, allowing a local attacker to\n  exploit racy stack unwinding and leak kernel task stack contents.\n  (bnc#1110785)\n\nThe following non-security bugs were fixed:\n\n- kabi: drop LINUX_MIB_TCPWQUEUETOOBIG snmp counter (bsc#1137586).\n- lib: add 'on'/'off' support to strtobool (bsc#1125931).\n- powerpc/tm: Add commandline option to disable hardware transactional memory (bsc#1125580).\n- powerpc/tm: Add TM Unavailable Exception (bsc#1125580).\n- powerpc/tm: Flip the HTM switch default to disabled (bsc#1125580).\n- powerpc/vdso32: fix CLOCK_MONOTONIC on PPC64 (bsc#1131587).\n- powerpc/vdso64: Fix CLOCK_MONOTONIC inconsistencies across Y2038 (bsc#1131587).\n- tcp: add tcp_min_snd_mss sysctl (bsc#1137586).\n- tcp: enforce tcp_min_snd_mss in tcp_mtu_probing() (bsc#1137586).\n- tcp: limit payload size of sacked skbs (bsc#1137586).\n- tcp: tcp_fragment() should apply sane memory limits (bsc#1137586).\n","id":"SUSE-SU-2019:1692-1","modified":"2019-06-24T19:01:10Z","published":"2019-06-24T19:01:10Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2019/suse-su-20191692-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1090078"},{"type":"REPORT","url":"https://bugzilla.suse.com/1110785"},{"type":"REPORT","url":"https://bugzilla.suse.com/1113769"},{"type":"REPORT","url":"https://bugzilla.suse.com/1120843"},{"type":"REPORT","url":"https://bugzilla.suse.com/1120885"},{"type":"REPORT","url":"https://bugzilla.suse.com/1125580"},{"type":"REPORT","url":"https://bugzilla.suse.com/1125931"},{"type":"REPORT","url":"https://bugzilla.suse.com/1131543"},{"type":"REPORT","url":"https://bugzilla.suse.com/1131587"},{"type":"REPORT","url":"https://bugzilla.suse.com/1132374"},{"type":"REPORT","url":"https://bugzilla.suse.com/1132472"},{"type":"REPORT","url":"https://bugzilla.suse.com/1134848"},{"type":"REPORT","url":"https://bugzilla.suse.com/1135281"},{"type":"REPORT","url":"https://bugzilla.suse.com/1136424"},{"type":"REPORT","url":"https://bugzilla.suse.com/1136446"},{"type":"REPORT","url":"https://bugzilla.suse.com/1137586"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-17972"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-11190"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-11477"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-11478"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-11479"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-11833"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-11884"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-3846"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-5489"}],"related":["CVE-2018-17972","CVE-2019-11190","CVE-2019-11477","CVE-2019-11478","CVE-2019-11479","CVE-2019-11833","CVE-2019-11884","CVE-2019-3846","CVE-2019-5489"],"summary":"Security update for the Linux Kernel","upstream":["CVE-2018-17972","CVE-2019-11190","CVE-2019-11477","CVE-2019-11478","CVE-2019-11479","CVE-2019-11833","CVE-2019-11884","CVE-2019-3846","CVE-2019-5489"]}
