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.

Kerberos FTP client allows remote FTP sites to execute arbitrary code via a pipe (|) character in a filename that is retrieved by the client.

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.

The processchpwrequest 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.

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)

Integer underflow flaws, leading to heap-based corruption, were found in the way MIT Kerberos Key Distribution Center (KDC) used to decrypt ciphertexts encrypted with Advanced Encryption Standard (AES) and ARCFOUR (RC4) encryption algorithms. A remote KDC client could provide a specially-crafted AES or RC4 encrypted ciphertext(s), which once processed by a central KDC would lead to denial of service (KDC crash or abort) or, potentially, to KDC relying authentication services compromise or arbitrary code execution with the privileges of the KDC centre.

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.

Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3 through 9.0, MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.2 and earlier, Heimdal 1.5.1 and earlier, GNU inetutils, and possibly other products allows remote attackers to execute arbitrary code via a long encryption key, as exploited in the wild in December 2011.

Buffer overflow in the RPC library used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.4 through 1.6.3 allows remote attackers to execute arbitrary code by triggering a large number of open file descriptors.

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.

MIT Lifelong Kindergarten Scratch scratch-vm before 0.2.0-prerelease.20200714185213 loads extension URLs from untrusted project.json files with certain characters, resulting in remote code execution because the URL's content is treated as a script and is executed as a worker. The responsible code is getExtensionIdForOpcode in serialization/sb3.js. The use of is incompatible with a protection mechanism in older versions, in which URLs were split and consequently deserialization attacks were prevented.

NOTE: the scratch.mit.edu hosted service is not affected because of the lack of worker scripts.

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.

Double free vulnerability in MIT Kerberos 5 (aka krb5) allows attackers to have unspecified impact via vectors involving automatic deletion of security contexts on error.

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

KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.

This affects the package scratch-svg-renderer before 0.2.0-prerelease.20201019174008. The loadString function does not escape SVG properly, which can be used to inject arbitrary elements into the DOM via the transformMeasurements function.

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.

Buffer overflow in the RPC library (lib/rpc/rpcdtablesize.c) used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.2.2, and probably other versions before 1.3, when running on systems whose unistd.h does not define the FDSETSIZE macro, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by triggering a large number of open file descriptors.

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."
