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.

An update of the gnutls package has been released.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtasn1: stack overflow in asn1_der_decoding (CVE-2015-2806)

  - libtasn1: Stack-based buffer overflow in asn1_find_node() (CVE-2017-6891)

  - The _asn1_extract_der_octet function in lib/decoding.c in GNU Libtasn1 before 4.5 allows remote attackers     to cause a denial of service (out-of-bounds heap read) via a crafted certificate. (CVE-2015-3622)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtasn1: Stack-based buffer overflow in asn1_find_node() (CVE-2017-6891)

  - 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. (CVE-2017-10790)

  - GNU Libtasn1-4.13 libtasn1-4.13 version libtasn1-4.13, libtasn1-4.12 contains a DoS, specifically CPU     usage will reach 100% when running asn1Paser against the POC due to an issue in
    _asn1_expand_object_id(p_tree), after a long time, the program will be killed. This attack appears to be     exploitable via parsing a crafted file. (CVE-2018-1000654)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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.
