The SUSE Linux Enterprise Server 11 SP3 Kernel for Teradata was updated to fix security issues and bugs:
The following security bugs have been fixed:
- CVE-2019-5489: 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 (bsc#1120843)
- CVE-2019-11190: 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 (bsc#1132472)
- CVE-2018-17972: 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 (bsc#1110785)
- CVE-2019-11884: 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. (bsc#1134848)
- CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions (bsc#1133188)
