The remote host is affected by the vulnerability described in GLSA-201110-05 (GnuTLS: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in GnuTLS. Please review the CVE identifiers referenced below for details.
Impact :
An attacker could perform man-in-the-middle attacks to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority or to inject an arbitrary amount of chosen plaintext into the beginning of the application protocol stream, allowing for further exploitation.
Workaround :
There is no known workaround at this time.
