The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2015-622:02 advisory.

    Kerberos V5 is a trusted-third-party network authentication system,     which can improve your network's security by eliminating the insecure     practice of sending passwords over the network in unencrypted form.
    Security issues fixed with this release:
    CVE-2014-5355     MIT Kerberos 5 (aka krb5) through 1.13.1 incorrectly expects that a     krb5_read_message data field is represented as a string ending with a     '\0' character, which allows remote attackers to (1) cause a denial of     service (NULL pointer dereference) via a zero-byte version string or     (2) cause a denial of service (out-of-bounds read) by omitting the     '\0' character, related to appl/user_user/server.c and     lib/krb5/krb/recvauth.c.
    CVE-2015-2694     The kdcpreauth modules in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x     before 1.13.2 do not properly track whether a client's request has     been validated, which allows remote attackers to bypass an intended     preauthentication requirement by providing (1) zero bytes of data or     (2) an arbitrary realm name, related to plugins/preauth/otp/main.c and     plugins/preauth/pkinit/pkinit_srv.c.
    Fixed bugs:
    * Previously, the RADIUS support (libkrad) in krb5 was sending krb5 authentication for Transmission     Control Protocol (TCP) transports multiple times, accidentally using a code path intended to be used only     for unreliable transport types, for example User Datagram Protocol (UDP) transports. A patch that fixes     the problem by disabling manual retries for reliable transports, such as TCP, has been applied, and the     correct code path is now used in this situation.
    * Attempts to use Kerberos single sign-on (SSO) to access SAP NetWeaver systems sometimes failed. The SAP     NetWeaver developer trace displayed the following error message:

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

krb5 was updated to fix four security issues.

These security issues were fixed :

  - CVE-2014-5353: NULL pointer dereference when using a     ticket policy name as password name (bsc#910457).

  - CVE-2014-5354: NULL pointer dereference when using     keyless entries (bsc#910458).

  - CVE-2014-5355: Denial of service in krb5_read_message     (bsc#918595).

  - CVE-2015-2694: OTP and PKINIT kdcpreauth modules leading     to requires_preauth bypass (bsc#928978).

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

A flaw was found in the OTP kdcpreauth module of MIT Kerberos. A remote attacker could use this flaw to bypass the requires_preauth flag on a client principal and obtain a ciphertext encrypted in the principal's long-term key. This ciphertext could be used to conduct an off-line dictionary attack against the user's password.

It was found that the krb5_read_message() function of MIT Kerberos did not correctly sanitize input, and could create invalid krb5_data objects. A remote, unauthenticated attacker could use this flaw to crash a Kerberos child process via a specially crafted request.

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.
