CVE-2003-0082 2 Mit, Redhat 4 Kerberos, Kerberos 5, Enterprise Linux and 1 more 2026-04-16 N/A
The Key Distribution Center (KDC) in Kerberos 5 (krb5) 1.2.7 and earlier allows remote, authenticated attackers to cause a denial of service (crash) on KDCs within the same realm using a certain protocol request that causes the KDC to corrupt its heap (aka "buffer underrun").

Certain weaknesses in the implementation of version 4 of the Kerberos protocol (krb4) in the krb5 distribution, when triple-DES keys are used to key krb4 services, allow an attacker to create krb4 tickets for unauthorized principals using a cut-and-paste attack and "ticket splicing."

Double free vulnerability in the krb5_rd_cred function for MIT Kerberos 5 (krb5) 1.3.1 and earlier may allow local users to execute arbitrary code.

The asn1buf_skiptail function in the ASN.1 decoder library for MIT Kerberos 5 (krb5) 1.2.2 through 1.3.4 allows remote attackers to cause a denial of service (infinite loop) via a certain BER encoding.
CVE-2004-0772 4 Debian, Mit, Openpkg and 1 more 4 Debian Linux, Kerberos 5, Openpkg and 1 more 2026-04-16 9.8 Critical
Double free vulnerabilities in error handling code in krb524d for MIT Kerberos 5 (krb5) 1.2.8 and earlier may allow remote attackers to execute arbitrary code.
CVE-2004-0971 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
The krb5-send-pr script in the kerberos5 (krb5) package in Trustix Secure Linux 1.5 through 2.1, and possibly other operating systems, allows local users to overwrite files via a symlink attack on temporary files.
CVE-2004-1189 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
The add_to_history function in svr_principal.c in libkadm5srv for MIT Kerberos 5 (krb5) up to 1.3.5, when performing a password change, does not properly track the password policy's history count and the maximum number of keys, which can cause an array index out-of-bounds error and may allow authenticated users to execute arbitrary code via a heap-based buffer overflow.
CVE-2005-0488 4 Microsoft, Mit, Redhat and 1 more 4 Telnet Client, Kerberos 5, Enterprise Linux and 1 more 2026-04-16 N/A
Certain BSD-based Telnet clients, including those used on Solaris and SuSE Linux, allow remote malicious Telnet servers to read sensitive environment variables via the NEW-ENVIRON option with a SEND ENV_USERVAR command.
CVE-2005-1174 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
MIT Kerberos 5 (krb5) 1.3 through 1.4.1 Key Distribution Center (KDC) allows remote attackers to cause a denial of service (application crash) via a certain valid TCP connection that causes a free of unallocated memory.
CVE-2005-1175 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-16 N/A
Heap-based buffer overflow in the Key Distribution Center (KDC) in MIT Kerberos 5 (krb5) 1.4.1 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a certain valid TCP or UDP request.

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.
