The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2015-8629 It was discovered that 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-2015-8630 It was discovered that 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-2015-8631 It was discovered that 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. For the oldstable distribution (wheezy), these problems have been fixed in version 1.10.1+dfsg-5+deb7u7. The oldstable distribution (wheezy) is not affected by CVE-2015-8630. For the stable distribution (jessie), these problems have been fixed in version 1.12.1+dfsg-19+deb8u2. We recommend that you upgrade your krb5 packages.
