Debian Security Advisory DSA-4607-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
January 20, 2020 https://www.debian.org/security/faq
Package : openconnect
CVE ID : CVE-2019-16239
Debian Bug : 940871
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.
For the detailed security status of openconnect please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/openconnect
