EulerOS 2.0 SP1 : krb5 (EulerOS-SA-2016-1012)

Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the krb5 packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :

- A memory leak flaw was found in the krb5_unparse_name()
function of the MIT Kerberos kadmind service. An
authenticated attacker could repeatedly send specially
crafted requests to the server, which could cause the
server to consume large amounts of memory resources,
ultimately leading to a denial of service due to memory

- An out-of-bounds read flaw was found in the kadmind
service of MIT Kerberos. An authenticated attacker
could send a maliciously crafted message to force
kadmind to read beyond the end of allocated memory, and
write the memory contents to the KDC database if the
attacker has write permission, leading to information
disclosure. (CVE-2015-8629)

- A NULL pointer dereference flaw was found in the
procedure used by the MIT Kerberos kadmind service to
store policies: the kadm5_create_principal_3() and
kadm5_modify_principal() function did not ensure that a
policy was given when KADM5_POLICY was set. An
authenticated attacker with permissions to modify the
database could use this flaw to add or modify a
principal with a policy set to NULL, causing the
kadmind service to crash. (CVE-2015-8630)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
