CVE-2013-1415: Mit Kerberos 5

Medium severity, CVSS 5.0. EPSS: 3.7% chance of exploitation in the next 30 days.

The pkinit_check_kdc_pkid function in plugins/preauth/pkinit/pkinit_crypto_openssl.c in the PKINIT implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.4 and 1.11.x before 1.11.1 does not properly handle errors during extraction of fields from an X.509 certificate, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a malformed KRB5_PADATA_PK_AS_REQ AS-REQ request.

Affected products

• Mit Kerberos 5: before 1.10.4 (fixed in 1.10.4); version 1.11 only
• Opensuse Opensuse: version 11.4 only
