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.

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)

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

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.
