security flaw

Kerberos 4 KDC program does not properly check for null termination of AUTH_MSG_KDC_REQUEST requests, which allows remote attackers to cause a denial of service via a malformed request.

security flaw

Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391.

security flaw

Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the e_msg variable in the kerb_err_reply function.

security flaw

Buffer overflow in krb425_conv_principal function in Kerberos 5 allows remote attackers to gain root privileges.

Buffer overflow in Kerberos IV compatibility libraries as used in Kerberos V allows local users to gain root privileges via a long line in a kerberos configuration file, which can be specified via the KRB_CONF environmental variable.

Kerberos 4 key servers allow a user to masquerade as another by breaking and generating session keys.

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.

Buffer overflow in cgicso.c for cgiemail 1.6 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long query parameter.

security flaw

The (1) krshd and (2) v4rcp applications in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, when running on Linux and AIX, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which allows local users to gain privileges by causing setuid to fail to drop privileges using attacks such as resource exhaustion.

security flaw

Double free vulnerability in the krb5_recvauth function in MIT Kerberos 5 (krb5) 1.4.1 and earlier allows remote attackers to execute arbitrary code via certain error conditions.

cgiemail allows remote attackers to use cgiemail as a spam proxy via CRLF injection of encoded newline (%0a) characters in parameters such as "required-subject," which can be used to modify the CC, BCC, and other header fields in the generated email message.

security flaw

Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the localrealm variable in the process_v4 function.

security flaw

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.

security flaw

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.

security flaw

The kadm_ser_in function in (1) the Kerberos v4compatibility administration daemon (kadmind4) in the MIT Kerberos 5 (krb5) krb5-1.2.6 and earlier, (2) kadmind in KTH Kerberos 4 (eBones) before 1.2.1, and (3) kadmind in KTH Kerberos 5 (Heimdal) before 0.5.1 when compiled with Kerberos 4 support, does not properly verify the length field of a request, which allows remote attackers to execute arbitrary code via a buffer overflow attack.

security flaw

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.

security flaw

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.

Buffer overflow in pks PGP public key web server before 0.9.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long search argument to the lookup capability.

security flaw

Buffer overflow in Kerberos 4 KDC program allows remote attackers to cause a denial of service via the lastrealm variable in the set_tgtkey function.

security flaw

Buffer overflow in krb_rd_req function in Kerberos 4 and 5 allows remote attackers to gain root privileges.
