"This update for glibc fixes the following issues :

  - A privilege escalation bug in the realpath() function
    has been fixed. [CVE-2018-1000001, bsc#1074293]

  - A memory leak and a buffer overflow in the dynamic ELF
    loader has been fixed. [CVE-2017-1000408,
    CVE-2017-1000409, bsc#1071319]

  - An issue in the code handling RPATHs was fixed that
    could have been exploited by an attacker to execute code
    loaded from arbitrary libraries. [CVE-2017-16997,
    bsc#1073231]

  - A potential crash caused by a use-after-free bug in
    pthread_create() has been fixed. [bsc#1053188]

  - A bug that prevented users to build shared objects which
    use the optimized libmvec.so API has been fixed.
    [bsc#1070905]

  - A memory leak in the glob() function has been fixed.
    [CVE-2017-15670, CVE-2017-15671, CVE-2017-15804,
    bsc#1064569, bsc#1064580, bsc#1064583]

  - A bug that would lose the syscall error code value in
    case of crashes has been fixed. [bsc#1063675]

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
