Mageia Linux Local Security Checks mgasa-2016-0052

Vulnerability Insight:
In all versions of MIT krb5, an authenticated attacker can cause kadmind to read beyond the end of allocated memory by sending a string without a terminating zero byte. Information leakage may be possible for an attacker with permission to modify the database (CVE-2015-8629). In MIT krb5 1.12 and later, an authenticated attacker with permission to modify a principal entry can cause kadmind to dereference a null pointer by supplying a null policy value but including KADM5_POLICY in the mask (CVE-2015-8630). In all versions of MIT krb5, an authenticated attacker can cause kadmind to leak memory by supplying a null principal name in a request which uses one. Repeating these requests will eventually cause kadmind to exhaust all available memory (CVE-2015-8631).

Solution:
Update the affected packages to the latest available version.

CVSS Score:
