The remote host is affected by the vulnerability described in GLSA-201702-04 (GnuTLS: Multiple vulnerabilities)
Multiple heap and stack overflows and double free vulnerabilities have been discovered in GnuTLS by the OSS-Fuzz project. Please review the CVE identifiers referenced below for details.
Impact :
A remote attacker could entice a user or automated system to process a specially crafted certificate using an application linked against GnuTLS.
This could possibly result in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround :
There is no known workaround at this time.
