Problem description

The SuSE Security Team has done a code review of the heimdal package. The following bugs has been discovered and fixed:
  • missing bounds checks in the ASN1 library
  • buffer and integer overflows in kdc and kadmin
  • various bugs in the krb5 library
Some of these bugs are considered to be exploitable by remote attackers. Since the primary targets of heimdal installations are authentication servers, a remote compromise is likely to also affect the complete network covered by these authentication servers. Thus an update is strongly recommended.


Please install the updates provided at the location noted below.
