The remote host is affected by the vulnerability described in GLSA-200707-11 (MIT Kerberos 5: Arbitrary remote code execution)

    kadmind is affected by multiple vulnerabilities in the RPC library     shipped with MIT Kerberos 5. It fails to properly handle zero-length     RPC credentials (CVE-2007-2442) and the RPC library can write past the     end of the stack buffer (CVE-2007-2443). Furthermore kadmind fails to     do proper bounds checking (CVE-2007-2798).
  Impact :

    A remote unauthenticated attacker could exploit these vulnerabilities     to execute arbitrary code with root privileges.
  Workaround :

    There is no known workaround at this time.

David Coffey discovered an uninitialized pointer free flaw in the RPC library used by kadmind. A remote unauthenticated attacker who could access kadmind could trigger the flaw causing kadmind to crash or possibly execute arbitrary code (CVE-2007-2442).

David Coffey also discovered an overflow flaw in the same RPC library.
A remote unauthenticated attacker who could access kadmind could trigger the flaw causing kadmind to crash or possibly execute arbitrary code (CVE-2007-2443).

Finally, a stack-based buffer overflow vulnerability was found in kadmind that allowed an unauthenticated user able to access kadmind the ability to trigger the vulnerability and possibly execute arbitrary code (CVE-2007-2798).

Updated packages have been patched to prevent this issue.

David Coffey discovered an uninitialized pointer free flaw in the RPC library used by kadmind. A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash or potentially execute arbitrary code as root. (CVE-2007-2442)

David Coffey also discovered an overflow flaw in the RPC library used by kadmind. On Scientific Linux, exploitation of this flaw is limited to a denial of service. A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash.
(CVE-2007-2443)

A stack-based buffer overflow flaw was found in kadmind. An authenticated attacker who can access kadmind could trigger this flaw and potentially execute arbitrary code on the Kerberos server.
(CVE-2007-2798)

David Coffey discovered an uninitialized pointer free flaw in the RPC library used by kadmind. On Scientific Linux 4 and 5, glibc detects attempts to free invalid pointers. A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash. (CVE-2007-2442)

The remote NewStart CGSL host, running version MAIN 6.06 (SP), 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)
