Description
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."
Affected configurations
• mit kerberos 5 (>= 1.8 < 1.19.4)
• mit kerberos 5 1.20
• heimdal project heimdal (< 7.7.1)
• samba samba (< 4.15.12)
• samba samba (>= 4.16.0 < 4.16.7)
• samba samba (>= 4.17.0 < 4.17.3)
