The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a
local attacker to exploit this vulnerability via a SUID-root binary and obtain
full root privileges (bsc#1108912)
- CVE-2018-14617: Prevent NULL pointer dereference and panic in
hfsplus_lookup() when opening a file (that is purportedly a hard link) in an
hfs+ filesystem that has malformed catalog data, and is mounted read-only
without a metadata directory (bsc#1102870)
- CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in
yurex_read allowed local attackers to use user access read/writes to crash the
kernel or potentially escalate privileges (bsc#1106095)
- CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was
caused by the way the overrun accounting works. Depending on interval and
expiry time values, the overrun can be larger than INT_MAX, but the accounting
is int based. This basically made the accounting values, which are visible to
user space via timer_getoverrun(2) and siginfo::si_overrun, random. This
allowed a local user to cause a denial of service (signed integer overflow) via
crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922)
- CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local
attackers to use a incorrect bounds check in the CDROM driver
CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)
- CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that
could have been used by local attackers to read kernel memory (bnc#1107689)
- CVE-2018-6555: The irda_setsockopt function allowed local users to cause a
denial of service (ias_object use-after-free and system crash) or possibly have
unspecified other impact via an AF_IRDA socket (bnc#1106511)
- CVE-2018-6554: Prevent memory leak in the irda_bind...
