A vulnerability has been found and corrected in krb5 :
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 (CVE-2011-0285).
The updated packages have been patched to correct this issue.
