CVE-2004-0643

CVE-2004-0643 describes a double-free vulnerability in MIT Kerberos 5 (krb5) prior to or at 1.3.1, specifically in krb5_rd_cred, potentially allowing arbitrary code execution on vulnerable KDC/clients. Connected advisories extend this class of issues to Kerberos KDC and libraries (double-free bug...

CVE-2004-0772

CVE-2004-0772 : The MIT Kerberos 5 implementation exposes double‑free vulnerabilities in the KDC (krb524d) and in the krb5 libraries for version 1.2.8 and earlier, potentially allowing a remote attacker to execute arbitrary code. Multiple connected advisories (Debian, Mandrake, Gentoo) confirm re...

CVE-2004-0642

MIT Kerberos 5 (krb5) is affected by CVE-2004-0642 due to double-free vulnerabilities in the ASN.1 decoder error handling for both the KDC library and the krb5 client library (versions 1.3.4 and earlier). The issue can allow remote attackers to execute arbitrary code, potentially compromising the...

CVE-2004-0642

Double free vulnerabilities in the error handling code for ASN.1 decoders in the 1 Key Distribution Center KDC library and 2 client library for MIT Kerberos 5 krb5 1.3.4 and earlier may allow remote attackers to execute arbitrary code...

CVE-2004-0644

The CVE-2004-0644 entry concerns MIT Kerberos 5 (krb5) 1.2.2–1.3.4, where the asn1buf_skiptail function in the ASN.1 decoder library allows remote attackers to cause a denial of service (infinite loop) via a specific BER encoding. Affected software includes the KDC and krb5 libraries; the impact ...

Mandrake Linux Security Advisory : krb5 (MDKSA-2004:088)

A double-free vulnerability exists in the MIT Kerberos 5's KDC program that could potentially allow a remote attacker to execute arbitrary code on the KDC host. As well, multiple double-free vulnerabilities exist in the krb5 library code, which makes client programs and application servers...

MIT krb5: Multiple vulnerabilities

Background MIT krb5 is the free implementation of the Kerberos network authentication protocol by the Massachusetts Institute of Technology. Description The implementation of the Key Distribution Center KDC and the MIT krb5 library contain double-free vulnerabilities, making client programs as we...

MIT Kerberos 5 ASN.1 decoding functions insecurely deallocate memory (double-free)

Overview The MIT Kerberos 5 library does not securely deallocate heap memory when decoding ASN.1 structures, resulting in double-free vulnerabilities. An unauthenticated, remote attacker could execute arbitrary code on a KDC server, which could compromise an entire Kerberos realm. An attacker may...

MIT Kerberos krb524d insecurely deallocates memory (double-free)

Overview The MIT Kerberos krb524d daemon does not securely deallocate heap memory when handling an error condition, resulting in a double-free vulnerability. An unauthenticated, remote attacker could execute arbitrary code on a system running krb524d, which in many cases is also a Kerberos...

MIT Kerberos 5 ASN.1 decoding function asn1buf_skiptail() does not properly terminate loop

Overview The asn1bufskiptail function in the MIT Kerberos 5 library does not properly terminate a loop, allowing an unauthenticated, remote attacker to cause a denial of service in a Kerberos Distribution Center KDC, application server, or Kerberos client. Description As described on the MIT...

MIT Kerberos 5 ASN.1 decoding function krb5_rd_cred() insecurely deallocates memory (double-free)

Overview The krb5rdcred function in the MIT Kerberos 5 library does not securely deallocate heap memory when decoding ASN.1 structures, resulting in a double-free vulnerability. A remote, authenticated attacker could execute arbitrary code or cause a denial of service on any system running an...
