EulerOS 2.0 SP8 : gnutls (EulerOS-SA-2019-1649)

high Nessus Plugin ID 126276

Language:

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 flaw was found in the way gnutls handled malformed TLS 1.3 asynchronous messages. An attacker could use this flaw to crash an application compiled with gnutls via invalid pointer access.NOTE: The gnutls versions 3.6.4 or later are affected by this issue.(CVE-2019-3836)

 - A double free flaw was found in the way the certificate verification API was implemented for gnutls. An attacker could cause a client or server application compiled against gnutls to crash by parsing a specially-crafted certificate.(CVE-2019-3829)

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.
