Package : openconnect
Version : 6.00-2+deb8u2
CVE ID : CVE-2020-12823
Debian Bug : 960620

OpenConnect, a VPN software, had a buffer overflow, causing a denial of
service (application crash) or possibly unspecified other impact, via
crafted certificate data to get_cert_name in gnutls.c.

For Debian 8 "Jessie", this problem has been fixed in version
6.00-2+deb8u2.

We recommend that you upgrade your openconnect packages.
