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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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)

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

    It was discovered that musl did not properly handle kernel syscalls. An attacker could use this     vulnerability to cause a denial of service (crash) or possibly execute arbitrary code. (CVE-2018-1000001)

    It was discovered that musl did not properly handle the parsing of DNS response codes. A remote attacker     could use this vulnerability to cause resource consumption (infinite loop), denial of service, or possibly     execute arbitrary code. This issue only affected Ubuntu 14.04 ESM. (CVE-2014-3484)

    It was discovered that musl did not properly handle the parsing of DNS response codes. A remote attacker     could use this vulnerability to cause resource consumption (infinite loop), denial of service, or possibly     execute arbitrary code. This issue only affected Ubuntu 16.04 ESM. (CVE-2017-15650)

    It was discovered that musl did not properly handle the parsing of ipv6 addresses. An attacker could use     this vulnerability to cause a denial of service (crash) or possibly execute arbitrary code. This issue     only affected Ubuntu 14.04 ESM. (CVE-2015-1817)

    It was discovered that TRE library, used by musl, did not properly handle certain inputs. An attacker     could use this vulnerability to cause a denial of service (crash). (CVE-2016-8859)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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

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)

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.

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
