Two vulnerabilities were discovered in Libtasn1, a library to manage ASN.1 structures, allowing a remote attacker to cause a denial of service against an application using the Libtasn1 library.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3547-1 advisory.

    It was discovered that Libtasn1 incorrectly handled certain files. If a user were tricked into opening a     crafted file, an attacker could possibly use this to cause a denial of service. This issue only affected     Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-10790)

    It was discovered that Libtasn1 incorrectly handled certain inputs. An attacker could possibly use this to     cause Libtasn1 to hang, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and     Ubuntu 17.10. (CVE-2018-6003)

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.

The remote host is affected by the vulnerability described in GLSA-201710-11 (GNU Libtasn1: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in GNU Libtasn1. Please       review the referenced CVE identifiers for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, or have       other unspecified impacts.
  Workaround :

    There is no known workaround at this time.

CVE-2017-10790 The _asn1_check_identifier function in GNU Libtasn1 through 4.12 causes a NULL pointer dereference and crash when reading crafted input that triggers assignment of a NULL value within an asn1_node structure. It may lead to a remote denial of service attack.

For Debian 7 'Wheezy', these problems have been fixed in version 2.13-2+deb7u5.

We recommend that you upgrade your libtasn1-3 packages.
