APP: Kerberos kpasswd process_chpw_request Denial Of Service
This signature detects attempts to exploit a known vulnerability against Kerberos. A successful attack can result in a denial-of-service condition.
Extended Description
The process_chpw_request function in schpw.c in the password-changing functionality in kadmind in MIT Kerberos 5 (aka krb5) 1.7 through 1.9 frees an invalid pointer, which allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a crafted request that triggers an error condition.
