Integer overflow in shadow 4.2.1 allows local users to gain privileges via crafted input to newuidmap.

According to the version of the shadow-utils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - Integer overflow in shadow 4.2.1 allows local users to     gain privileges via crafted input to     newuidmap.(CVE-2016-6252)

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

According to the versions of the shadow-utils package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In shadow before 4.5, the newusers tool could be made     to manipulate internal data structures in ways     unintended by the authors. Malformed input may lead to     crashes (with a buffer overflow or other memory     corruption) or other unspecified behaviors. This     crosses a privilege boundary in, for example, certain     web-hosting environments in which a Control Panel     allows an unprivileged user account to create     subaccounts.(CVE-2017-12424)

  - Integer overflow in shadow 4.2.1 allows local users to     gain privileges via crafted input to     newuidmap.(CVE-2016-6252)

The remote host is affected by the vulnerability described in GLSA-201706-02 (Shadow: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Shadow. Please review       the CVE identifiers referenced below for details.
  Impact :

    A local attacker could possibly cause a Denial of Service condition,       gain privileges via crafted input, or SIGKILL arbitrary processes.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3276-1 advisory.

    Sebastian Krahmer discovered integer overflows in shadow utilities. A local attacker could possibly cause     them to crash or potentially gain privileges via crafted input. (CVE-2016-6252)

    Tobias Stckmann discovered a race condition in su. A local attacker could cause su to send SIGKILL to     other processes with root privileges. (CVE-2017-2616)

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.

Several vulnerabilities were discovered in the shadow suite. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2016-6252     An integer overflow vulnerability was discovered,     potentially allowing a local user to escalate privileges     via crafted input to the newuidmap utility.

  - CVE-2017-2616     Tobias Stoeckmann discovered that su does not properly     handle clearing a child PID. A local attacker can take     advantage of this flaw to send SIGKILL to other     processes with root privileges, resulting in denial of     service.
