Package        : openconnect
Version        : 6.00-2+deb8u1
CVE ID         : CVE-2019-16239
Debian Bug     : 940871


A vulnerability was discovered by Lukas Kupczyk of the Advanced Research
Team at CrowdStrike Intelligence in OpenConnect, an open client for
Cisco AnyConnect, Pulse, GlobalProtect VPN.  A malicious HTTP server
(after its identity certificate has been accepted) can provide bogus
chunk lengths for chunked HTTP encoding and cause a heap overflow.

For Debian 8 "Jessie", this problem has been fixed in version
6.00-2+deb8u1.

We recommend that you upgrade your openconnect packages.
