  "details" : [ "PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has \"a similar bug.\"", "A vulnerability was found in MIT krb5. This flaw allows an authenticated attacker to cause a KDC or kadmind process to crash by reading beyond the bounds of allocated memory, creating a denial of service. A privileged attacker may similarly be able to cause a Kerberos or GSS application service to crash." ],
