EulerOS 2.0 SP1 : gnutls (EulerOS-SA-2017-1203)

critical Nessus Plugin ID 103061

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- A double-free flaw was found in the way GnuTLS parsed certain X.509 certificates with Proxy Certificate Information extension. An attacker could create a specially-crafted certificate which, when processed by an application compiled against GnuTLS, could cause that application to crash. (CVE-2017-5334)

- Multiple flaws were found in the way gnutls processed OpenPGP certificates. An attacker could create specially crafted OpenPGP certificates which, when parsed by gnutls, would cause it to crash.
(CVE-2017-5335, CVE-2017-5336, CVE-2017-5337, CVE-2017-7869)

- A null pointer dereference flaw was found in the way GnuTLS processed ClientHello messages with status_request extension. A remote attacker could use this flaw to cause an application compiled with GnuTLS to crash. (CVE-2017-7507)

- A flaw was found in the way GnuTLS validated certificates using OCSP responses. This could falsely report a certificate as valid under certain circumstances. (CVE-2016-7444)

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.

Solution

Update the affected gnutls packages.
