CVE Descriptions
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.

EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

MIT Kerberos is prone to a remote code-execution vulnerability in 'kadmind'.
An attacker may exploit this issue to execute arbitrary code with superuser privileges. Failed attempts will cause the affected application to crash, denying service to legitimate users. A successful exploit will completely compromise affected computers.
MIT Kerberos 5 1.7 and later are vulnerable.
NOTE (April 13, 2011): This BID was originally titled 'MIT Kerberos kadmind Version String Processing Remote Denial Of Service Vulnerability', but has been renamed to better reflect the nature of the issue.
