It was discovered that there were was a regression introduced in DLA-2145-1 due to the incorrect application of the upstream patch for CVE-2020-10108 & CVE-2020-10109 regarding a number of HTTP request splitting vulnerabilities in Twisted, an Python event-based framework for building various types of internet applications.

Thanks to Etienne Allovon for the detailed report.

For Debian 8 ‘Jessie’, these issues have been fixed in twisted version 14.0.2-3+deb8u2.

We recommend that you upgrade your twisted packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
