The SUSE Linux Enterprise 11 SP3 Teradata kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-14617: There is a NULL pointer dereference and panic in hfsplus_lookup() in fs/hfsplus/dir.c 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 (bnc#1102870). - CVE-2018-16276: An issue was discovered in yurex_read in drivers/usb/misc/yurex.c where local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges (bnc#1106095). - CVE-2018-12896: An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is 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. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922).
The following non-security bugs were fixed:
- x86/fpu: Do not do __thread_fpu_end() if use_eager_fpu() (bnc#1109967). - x86/fpu: fix signal handling with eager FPU switching (ia32) (bsc#1108227).
