paul Posted January 15, 2010 Report Share Posted January 15, 2010 Multiple vulnerabilities has been found and corrected in krb5: The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.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 (CVE-2009-0846). The asn1buf_imbed function in the ASN.1 decoder in MIT Kerberos 5 (aka krb5) 1.6.3, when PK-INIT is used, allows remote attackers to cause a denial of service (application crash) via a crafted length value that triggers an erroneous malloc call, related to incorrect calculations with pointer arithmetic (CVE-2009-0847). The updated packages have been patched to correct these issues. Link to comment Share on other sites More sharing options...
