Detail

Lukas Kupczyk reported a vulnerability in the handling of chunked HTTP in openconnect, an open client for Cisco AnyConnect, Pulse and GlobalProtect VPN. A malicious HTTP server (after having accepted its identity certificate), can provide bogus chunk lengths for chunked HTTP encoding and cause a heap-based buffer overflow.

For the oldstable distribution (stretch), this problem has been fixed in version 7.08-1+deb9u1.

For the stable distribution (buster), this problem has been fixed in version 8.02-1+deb10u1.

We recommend that you upgrade your openconnect packages.
