COMPLETE Summary
The original patch for CVE-2007-3999 in svc_auth_gss.c in the RPCSEC_GSS RPC library in MIT Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration daemon (kadmind) and other applications that use krb5, does not correctly check the buffer length in some environments and architectures, which might allow remote attackers to conduct a buffer overflow attack.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2007-0892.NASL description Updated krb5 packages that correct a security flaw are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. Kerberos is a network authentication system which allows clients and servers to authenticate to each other through use of symmetric encryption and a trusted third party, the KDC. kadmind is the KADM5 administration server. The MIT Kerberos Team discovered a problem with the originally published patch for svc_auth_gss.c (CVE-2007-3999). A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash. On Red Hat Enterprise Linux 5 it is not possible to exploit this flaw to run arbitrary code as the overflow is blocked by FORTIFY_SOURCE. (CVE-2007-4743) This issue did not affect the versions of Kerberos distributed with Red Hat Enterprise Linux 2.1, 3, or 4.

This update has been rated as having important security impact by the Red Hat Security Response Team. Kerberos is a network authentication system which allows clients and servers to authenticate to each other through use of symmetric encryption and a trusted third party, the KDC. kadmind is the KADM5 administration server. The MIT Kerberos Team discovered a problem with the originally published patch for svc_auth_gss.c (CVE-2007-3999). A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash. On Red Hat Enterprise Linux 5 it is not possible to exploit this flaw to run arbitrary code as the overflow is blocked by FORTIFY_SOURCE. (CVE-2007-4743) This issue did not affect the versions of Kerberos distributed with Red Hat Enterprise Linux 2.1, 3, or 4. Users of krb5-server are advised to update to these erratum packages which contain a corrected backported fix for this issue. last seen 2020-06-01 modified 2020-06-02 plugin id 43652 published 2010-01-06 reporter This script is Copyright (C) 2010-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/43652 title CentOS 5 : krb5 (CESA-2007:0892) NASL family Mandriva Local Security Checks NASL id MANDRAKE_MDKSA-2007-174.NASL description A stack-based buffer overflow vulnerability was discovered in the RPC library used by Kerberos last seen 2020-06-01 modified 2020-06-02 plugin id 26006 published 2007-09-07 reporter This script is Copyright (C) 2007-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/26006 title Mandrake Linux Security Advisory : krb5 (MDKSA-2007:174-1) NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-511-2.NASL description USN-511-1 fixed vulnerabilities in krb5 and librpcsecgss. The fixes were incomplete, and only reduced the scope of the vulnerability, without fully solving it. This update fixes the problem. It was discovered that the libraries handling RPCSEC_GSS did not correctly validate the size of certain packet structures. An unauthenticated remote user could send a specially crafted request and execute arbitrary code with root privileges. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 28116 published 2007-11-10 reporter Ubuntu Security Notice (C) 2007-2019 Canonical, Inc. / NASL script (C) 2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/28116 title Ubuntu 6.06 LTS / 6.10 / 7.04 : krb5, librpcsecgss vulnerability (USN-511-2)
