An update of the krb5 package has been released.

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

  - plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT     Kerberos 5 (aka krb5) through 1.15.2 mishandles     Distinguished Name (DN) fields, which allows remote     attackers to execute arbitrary code or cause a denial     of service (buffer overflow and application crash) in     situations involving untrusted X.509 data, related to     the get_matching_data and X509_NAME_oneline_ex     functions. (CVE-2017-15088)

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.

Fix CVE-2017-15088 (Buffer overflow in get_matching_data())

----

Remove build dependency on python-pyrad. It is only used on the test suite, and we gracefully skip the tests if it is not present.

An update of 'krb5', 'libjpeg-turbo', 'libtiff' packages of Photon OS has been released.

This update for krb5 fixes the following securitz issue&Ouml;

  - CVE-2017-15088: A buffer overflow in get_matching_data()     was fixed that could under specific circumstances be     used to execute code (bsc#1065274)

This update was imported from the SUSE:SLE-12-SP2:Update update project.

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

  - null dereference in kadmind or DN container check     bypass by supplying special crafted data     (CVE-2018-5729)

  - DN container check bypass by supplying special crafted     data (CVE-2018-5730)

  - A stack based buffer overflow was found in the     get_matching_data() function, when reading the     principal's certificate during pkinit     preauthentication. If the Certifcate Authority's     subject line is sufficiently long, an attacker able to     have a specially crafted certificate signed could crash     the authentication process, such as kinit, or,     possibly, run arbitrary code.(CVE-2017-15088 )

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles     Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial     of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related     to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use     cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin     code that is specific to Red Hat. (CVE-2017-15088)

Note that Nessus relies on the presence of the package as reported by the vendor.
