This update includes the following fixes :

  - fix for CVE-2016-8859

  - fix for CVE-2015-3796 (see     https://github.com/laurikari/tre/issues/37 and     https://bugs.chromium.org/p/project-zero/issues/detail?i     d=428)

  - fix for parallel installation of multilib packages

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4768-1 advisory.

  - Multiple stack-based buffer overflows in the __dn_expand function in network/dn_expand.c in musl libc 1.1x     before 1.1.2 and 0.9.13 through 1.0.3 allow remote attackers to (1) have unspecified impact via an invalid     name length in a DNS response or (2) cause a denial of service (crash) via an invalid name length in a DNS     response, related to an infinite loop with no output. (CVE-2014-3484)

  - Stack-based buffer overflow in the inet_pton function in network/inet_pton.c in musl libc 0.9.15 through     1.0.4, and 1.1.0 through 1.1.7 allows attackers to have unspecified impact via unknown vectors.
    (CVE-2015-1817)

  - Multiple integer overflows in the TRE library and musl libc allow attackers to cause memory corruption via     a large number of (1) states or (2) tags, which triggers an out-of-bounds write. (CVE-2016-8859)

  - musl libc before 1.1.17 has a buffer overflow via crafted DNS replies because dns_parse_callback in     network/lookup_name.c does not restrict the number of addresses, and thus an attacker can provide an     unexpected number by sending A records in a reply to an AAAA query. (CVE-2017-15650)

  - In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to     write before the destination buffer leading to a buffer underflow and potential code execution.
    (CVE-2018-1000001)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for tre fixes one issue.

This security issue was fixed :

  - CVE-2016-8859: Fixed multiple integer overflows which     allowed attackers to cause memory corruption via a large     number of (1) states or (2) tags, which triggered an     out-of-bounds write (boo#1005483)

This update introduces kubernetes version 1.14.1 and cri-o 1.17.1 to Leap 15.1.

The remote host is affected by the vulnerability described in GLSA-201701-11 (musl: Integer overflow)

    A vulnerability was discovered in musl&rsquo;s tre_tnfa_run_parallel       function buffer overflow logic, due to the incorrect use of integer types       and missing overflow checks.
  Impact :

    An attacker, who controls the regular expression and/or string being       searched, could execute arbitrary code with the privileges of the       process.
  Workaround :

    There is no known workaround at this time.

A vulnerability has been found in the tre package that could allow an attacker to perform controlled heap corruption.

For Debian 7 'Wheezy', these problems have been fixed in version 0.8.0-3+deb7u1.

We recommend that you upgrade your tre packages.
