The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2810-1 advisory.

    It was discovered that the Kerberos kpasswd service incorrectly handled certain UDP packets. A remote     attacker could possibly use this issue to cause resource consumption, resulting in a denial of service.
    This issue only affected Ubuntu 12.04 LTS. (CVE-2002-2443)

    It was discovered that Kerberos incorrectly handled null bytes in certain data fields. A remote attacker     could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 12.04 LTS and     Ubuntu 14.04 LTS. (CVE-2014-5355)

    It was discovered that the Kerberos kdcpreauth modules incorrectly tracked certain client requests. A     remote attacker could possibly use this issue to bypass intended preauthentication requirements. This     issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-2694)

    It was discovered that Kerberos incorrectly handled certain SPNEGO packets. A remote attacker could     possibly use this issue to cause a denial of service. (CVE-2015-2695)

    It was discovered that Kerberos incorrectly handled certain IAKERB packets. A remote attacker could     possibly use this issue to cause a denial of service. (CVE-2015-2696, CVE-2015-2698)

    It was discovered that Kerberos incorrectly handled certain TGS requests. A remote attacker could possibly     use this issue to cause a denial of service. (CVE-2015-2697)

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 NewStart CGSL host, running version MAIN 6.06, has krb5 packages installed that are affected by multiple vulnerabilities:

  - plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles     Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial     of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related     to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use     cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin     code that is specific to Red Hat. (CVE-2017-15088)

  - The process_chpw_request function in schpw.c in the password-changing functionality in kadmind in MIT     Kerberos 5 (aka krb5) 1.7 through 1.9 frees an invalid pointer, which allows remote attackers to execute     arbitrary code or cause a denial of service (daemon crash) via a crafted request that triggers an error     condition. (CVE-2011-0285)

  - schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5) before 1.11.3 does not properly     validate UDP packets before sending responses, which allows remote attackers to cause a denial of service     (CPU and bandwidth consumption) via a forged packet that triggers a communication loop, as demonstrated by     krb_pingpong.nasl, a related issue to CVE-1999-0103. (CVE-2002-2443)

  - The (1) ftpd and (2) ksu programs in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and (b)     Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to     gain privileges by causing setuid to fail to drop privileges. NOTE: as of 20060808, it is not known     whether an exploitable attack scenario exists for these issues. (CVE-2006-3084)

  - The RPC library in Kerberos 5 1.4 through 1.4.4, and 1.5 through 1.5.1, as used in Kerberos administration     daemon (kadmind) and other products that use this library, calls an uninitialized function pointer in     freed memory, which allows remote attackers to cause a denial of service (crash) and possibly execute     arbitrary code via unspecified vectors. (CVE-2006-6143)

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

The krb5 package was update to fix the following security issue :

  - CVE-2015-2698: Fixed a memory corruption regression     introduced by resolution of CVE-2015-2698 (bsc#954204).
