Summary:
Several security issues were fixed in Twisted.
Software Description:
- twisted: Event-based framework for internet applications
Details:
It was discovered that Twisted incorrectly escaped host headers in certain
404 responses. A remote attacker could possibly use this issue to perform
HTML and script injection attacks. This issue only affected Ubuntu 20.04
LTS and Ubuntu 22.04 LTS. (CVE-2022-39348)
It was discovered that Twisted incorrectly handled response order when
processing multiple HTTP requests. A remote attacker could possibly use
this issue to delay responses and manipulate the responses of second
requests. (CVE-2023-46137)
