Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) gopendir, (2) glstat, (3) gstat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
GSSFTP FTP daemon in Kerberos 5 1.1.x does not properly restrict access to some FTP commands, which allows remote attackers to cause a denial of service, and local users to gain root privileges.
Buffer overflow in krbrdreq function in Kerberos 4 and 5 allows remote attackers to gain root privileges.
Buffer overflow in krb425convprincipal function in Kerberos 5 allows remote attackers to gain root privileges.
Buffer overflow in krshd in Kerberos 5 allows remote attackers to gain root privileges.
The kadmserin 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.
Multiple buffer overflows in krb5anametolocalname for MIT Kerberos 5 (krb5) 1.3.3 and earlier allow remote attackers to execute arbitrary code as root.
MIT notified us of kadmind RPC lib buffer overflow, uninitialized pointer. Will be public on 04 September 2007, at 14:00 US/Eastern time.
This issue has not been triaged as it may well affect recent RHEL distributions with a different severity (flaw type is likely caught by fortifysource)
The gssrpcsvcauthgssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup.
The telnet daemon (telnetd) in MIT krb5 before 1.6.1 allows remote attackers to bypass authentication and gain system access via a username beginning with a '-' character, a similar issue to CVE-2007-0882.
The asn1decodegeneraltime function in lib/krb5/asn.1/asn1decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.
Integer overflow in the svcauthgssgetprincipal function in lib/rpc/svcauthgss.c in MIT Kerberos 5 (krb5) allows remote attackers to have an unknown impact via a large length value for a GSS client name in an RPC request.
The original patch for CVE-2007-3999 in svcauthgss.c in the RPCSECGSS 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.
Double free vulnerability in the krb5recvauth function in MIT Kerberos 5 (krb5) 1.4.1 and earlier allows remote attackers to execute arbitrary code via certain error conditions.
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.
A buffer overflow vulnerability was found in getmatchingdata() function when both the CA cert and the user cert have a long subject affecting krb5 that includes certauth plugin. Attack requires a validated certificate with a long subject and issuer, and a "pkinitcertmatch" string attribute on some principal in the database. A remote code execution exploit might also require that the attacker gets to choose the contents of the issuer in the validated cert.
Bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=871698
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.
The kdchandleprotectednegotiation function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8.x, 1.9.x before 1.9.5, and 1.10.x before 1.10.3 attempts to calculate a checksum before verifying that the key type is appropriate for a checksum, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized pointer free, heap memory corruption, and daemon crash) via a crafted AS-REQ request.
DISPUTED The reply function in ftpd.c in the gssftp ftpd in MIT Kerberos 5 (krb5) does not initialize the length variable when authtype has a certain value, which has unknown impact and remote authenticated attack vectors. NOTE: the original disclosure misidentifies the conditions under which the uninitialized variable is used. NOTE: the vendor disputes this issue, stating " The 'length' variable is only uninitialized if 'authtype' is neither the 'KERBEROSV4' nor 'GSSAPI'; this condition cannot occur in the unmodified source code."
In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can cause invalid memory reads during GSS message token handling by sending message tokens with invalid length fields.
The processasreq function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x before 1.10.3 does not initialize a certain structure member, which allows remote attackers to cause a denial of service (uninitialized pointer dereference and daemon crash) or possibly execute arbitrary code via a malformed AS-REQ request.
Stack-based buffer overflow in the renameprincipal2svc function in kadmind for MIT Kerberos 1.5.3, 1.6.1, and other versions allows remote authenticated users to execute arbitrary code via a crafted request to rename a principal.
Double free vulnerability in the GSS-API library (lib/gssapi/krb5/k5unseal.c), as used by the Kerberos administration daemon (kadmind) in MIT krb5 before 1.6.1, when used with the authentication method provided by the RPCSECGSS RPC library, allows remote authenticated users to execute arbitrary code and modify the Kerberos key database via a message with an "an invalid direction encoding".
Stack-based buffer overflow in the krb5klogsyslog function in the kadm5 library, as used by the Kerberos administration daemon (kadmind) and Key Distribution Center (KDC), in MIT krb5 before 1.6.1 allows remote authenticated users to execute arbitrary code and modify the Kerberos key database via crafted arguments, possibly involving certain format string specifiers.
The authgssapiunwrapdata function in lib/rpc/authgssapimisc.c in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 does not properly handle partial XDR deserialization, which allows remote authenticated users to cause a denial of service (use-after-free and double free, and daemon crash) or possibly execute arbitrary code via malformed XDR data, as demonstrated by data sent to kadmind.
Double free vulnerability in the krb5defstoremkey function in lib/kdb/kdbdefault.c in MIT Kerberos 5 (krb5) 1.5 has unknown impact and remote authenticated attack vectors. NOTE: the free operations occur in code that stores the krb5kdc master key, and so the attacker must have privileges to store this key.
kdc/dotgsreq.c in MIT Kerberos 5 (aka krb5) 1.21 before 1.21.2 has a double free that is reachable if an authenticated user can trigger an authorization-data handling failure. Incorrect data is copied from one ticket to another.
MIT notified us of a kadmind uninitialized pointer. Will be public on 04 September 2007, at 14:00 US/Eastern time.
This issue has not been triaged as it may well affect recent RHEL distributions with a different severity (flaw type is likely caught by fortifysource)
Off-by-one error in the krb5encodekrbsecretkey function in plugins/kdb/ldap/libkdbldap/ldapprincipal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka krb5) 1.6.x through 1.11.x before 1.11.6 and 1.12.x before 1.12.2 allows remote authenticated users to cause a denial of service (buffer overflow) or possibly execute arbitrary code via a series of "cpw -keepold" commands.
