Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- A use-after-free vulnerability exists in libcurl when an application configures an HTTP/2 stream-
dependency tree via `CURLOPT_STREAM_DEPENDS` or `CURLOPT_STREAM_DEPENDS_E`, subsequently invokes
`curl_easy_reset()`, and finally terminates the handle with `curl_easy_cleanup()`. During this final
cleanup phase, libcurl attempts to access and modify an internal structure that was already freed during
the reset operation. (CVE-2026-10536)

Solution

Update the curl library and its related packages to version 1:8.22.0-1+e1 or later.
